   Proposed structure: two right-handed helical chains of phosphate diester groups joining beta-D-deoxyribofuranose residues with 3',5' linkages, coiled round the same axis; the atoms of the two chains run in opposite directions; bases are on the inside and phosphates on the outside; adenine pairs with thymine and guanine with cytosine by hydrogen bonds, so the sequence of one chain determines the sequence of the other. The authors state that the structure must be regarded as unproved until checked against more exact results.

   Review. The standard genetic code maps 64 codons, each a triplet of nucleotides, to 20 amino acids and two punctuation marks, start and stop signals; 61 codons code for amino acids and three are stop codons; the code is shared, with relatively minor modifications, by all known life forms. Selenocysteine and pyrrolysine are encoded by special schemes in subsets of organisms.

   Reviewed human UniProtKB entries, release 2026_03, read through rest.uniprot.org on 2026-10-21. POLR2A (P24928): catalytic core component of RNA polymerase II, which synthesises mRNA precursors from the four ribonucleoside triphosphates, appends one nucleotide at a time to the 3' end of the nascent RNA on the basis of complementarity with the template DNA strand, uses two Mg2+ ions, and cooperates in co-transcriptional 5'-end capping and co-transcriptional splicing. RNGTT (O60942): removes the gamma-phosphate from the 5'-triphosphate end of nascent mRNA and transfers the GMP moiety of GTP to the 5'-diphosphate end. RNMT (O43148): methylates the N7 position of the added guanosine of the 5' cap with S-adenosyl-L-methionine. PAPOLA (P51003): creates the 3' poly(A) tail of mRNAs from ATP. EIF1 (P41567): component of the 43S pre-initiation complex, which binds the cap-proximal region, scans the 5' untranslated region and locates the initiation codon; essential for start-codon recognition on the basis of AUG nucleotide context and location relative to the cap. EEF1A1 (P68104): catalyses the GTP-dependent binding of aminoacyl-tRNA to the ribosomal A site; codon-anticodon base pairing promotes GTP hydrolysis; the ribosome then forms the peptide bond. EEF2 (P13639): catalyses the GTP-dependent ribosomal translocation step. DNMT1 (P26358): methylates CpG residues, preferentially hemimethylated DNA, and associates with replication sites in S phase, maintaining the methylation pattern on the newly synthesised strand.

   Expert-authored, peer-reviewed chapter, first posted 2 January 2014, comprehensive update 7 July 2022, revised 30 January 2025. APOB-, LDLR- and PCSK9-related familial hypercholesterolaemia is inherited in an autosomal dominant manner. Pathogenic LDLR variants account for more than 50% of FH; of pathogenic LDLR variants, about 85% are identified by sequence analysis, which detects missense, nonsense and splice-site variants and small intragenic deletions/insertions, and about 15% by gene-targeted deletion/duplication analysis, which detects intragenic deletions or duplications. Heterozygous LDLR-related FH: LDL cholesterol often above 190 mg/dL. Biallelic LDLR pathogenic variants: untreated adults often have LDL cholesterol above 500 mg/dL (above 13 mmol/L), and most develop severe coronary artery disease by their mid-20s.

   Expert-authored, peer-reviewed chapter, first posted 2000, comprehensive update 13 March 2025, revised 20 November 2025. Autosomal recessive; biallelic PAH variants; PAH at 12q23.2. Phenylketonuria denotes untreated plasma phenylalanine above 1,000 umol/L; untreated or late-diagnosed disease causes irreversible intellectual disability, seizures and microcephaly. Defects of tetrahydrobiopterin synthesis or recycling (GCH1, PTS, QDPR, PCBD1) account for about 2% of raised blood phenylalanine. Newborn screening uses dried blood spots collected 24 to 72 hours after birth, with phenylalanine and tyrosine measured by tandem mass spectrometry; biochemical diagnosis requires blood phenylalanine above 120 umol/L and a phenylalanine-to-tyrosine ratio of 3 or more. Treatment: phenylalanine-restricted diet with phenylalanine-free protein supplements based on amino acids or glycomacropeptide; 25% to 50% respond to sapropterin, a synthetic form of tetrahydrobiopterin; pegvaliase, a PEGylated phenylalanine ammonia lyase given subcutaneously, is approved in the US for adults with phenylalanine above 600 umol/L. Aspartame is metabolised in the gut to phenylalanine and aspartate. Maternal phenylalanine consistently above 360 umol/L in pregnancy causes intellectual disability in more than 90% of offspring. The chapter attributes brain toxicity to phenylacetic, phenylpyruvic and phenyllactic acids and to tyrosine and neurotransmitter deficiency.

    Expert-authored, peer-reviewed chapter, first posted 15 September 2003, comprehensive update 17 November 2022, revised 13 February 2025. Sickle haemoglobin (HbS) results from HBB c.20A>T, p.Glu6Val in the hemoglobin convention that starts numbering after the initiator methionine (p.Glu7Val in standard HGVS numbering). Sickle cell disease is inherited in an autosomal recessive manner; Hb S/S is the most common form. In deoxygenated HbS, an interaction between Val6 and complementary regions on adjacent molecules forms highly ordered, insoluble polymers that distort red blood cells; HbS polymerises in the T conformation associated with deoxygenation but not in the R conformation. Heterozygotes (Hb A/S, sickle cell trait) are not anaemic, have normal red cell indices and HbS near 40%, and Hb A/S confers a survival advantage in children who contract malaria.

    Narrative review. Cholesterol is a 27-carbon, four-ring molecule synthesised from acetate, a two-carbon unit attached to CoA; HMG-CoA reductase catalyses the rate-controlling step. An LDL particle contains about 1500 cholesteryl ester molecules in its core and a coat of about 800 phospholipid molecules, about 500 unesterified cholesterol molecules and one 500-kDa apoB. LDL receptors cluster in coated pits; internalised LDL reaches lysosomes, where cholesteryl esters are hydrolysed. The LDLR gene on the short arm of chromosome 19 has 18 exons and encodes a mature protein of 839 amino acids with seven cysteine-rich LDL-binding repeats and a 50-amino-acid cytoplasmic tail that directs it to coated pits. FH heterozygotes have half the functional receptors and about twofold LDL. Nuclear SREBP-2 activates the LDL receptor gene and the cholesterol biosynthetic genes; statins lower ER cholesterol, activate SREBP-2, raise hepatic LDL receptors and lower plasma LDL. Most LDL is removed by hepatic LDL receptors. PCSK9 binds hepatic LDL receptors and disrupts their recycling. African-Americans heterozygous for PCSK9 nonsense mutations Y142X or C679X had 28% lower LDL and 88% fewer heart attacks. Conclusions on human liver are extrapolated from rats, mice, hamsters and dogs.

    Of 24 Japanese livers, all 10 with active ALDH2 were ALDH2*1/*1; of the 14 without ALDH2 activity, 13 were heterozygous for ALDH2*2 and 1 homozygous, so the allele is dominant. ALDH2 is a homotetramer with a Km for acetaldehyde of about 1 µM; random association of equally expressed subunits would leave 6% fully normal tetramers in heterozygotes.

    In most humans lactase-phlorizin hydrolase, which hydrolyses lactose into glucose and galactose in the small intestine, declines after weaning. Lactase persistence is inherited as a dominant trait in Europeans and its frequency exceeds 90% in Swedes and Danes, is about 50% in Spanish and French populations and about 1% in Chinese. C/T-13910 lies about 14 kb upstream of LCT within MCM6. Three African variants, G/C-14010, T/G-13915 and C/G-13907, arose on different haplotypes, are associated with lactase persistence and raise LCT promoter activity in vitro by about 18-30%; selection coefficients 0.04-0.097.

    Class I ADH1A, ADH1B and ADH1C catalyse most hepatic ethanol oxidation; cytochrome P450s and catalase make only minor contributions. In vitro at pH 7.5, ADH1B*1 Km 0.013 mM and Vmax 5.2 per min; ADH1B*2 (rs1229984, His48) Km 1.8 mM and Vmax 190 per min; ADH1B*3 (rs2066702, Cys370) found almost exclusively in people of African origin. European carriers of ADH1B*2 eliminate ethanol about 14% faster. ALDH2 is a mitochondrial homotetramer with Km for acetaldehyde 0.2 µM; blood acetaldehyde is about 3 µM or less with active ALDH2 and 30 to 75 µM or higher in ALDH2*2 carriers. ALDH2*2 (rs671) has lysine at position 504 of the precursor (487 of the mature protein); a single ALDH2*2 subunit renders the tetramer nearly inactive; disulfiram inhibits ALDH2. rs671 allele frequency 0.160 in Han Chinese in Beijing, 0.271 in Southern Han Chinese, 0.240 in Japanese in Tokyo, 0.008 or less in the African, American, European and South Asian 1000 Genomes populations. Odds ratio for alcohol dependence 0.22 in ALDH2*2 heterozygotes (meta-analysis of 22 datasets).

    About 36% of East Asians show facial flushing, nausea and tachycardia after drinking, predominantly from ALDH2 deficiency; at least 540 million people, about 8% of the world population, are estimated to be ALDH2-deficient. In case-control studies from Japan and Taiwan, low-activity ALDH2 heterozygotes who drink have odds ratios of 3.7 to 18.1 for oesophageal squamous cell carcinoma after adjustment for alcohol consumption; ALDH2 deficiency does not influence oesophageal cancer risk in non-drinkers.

    Perspective with new analysis. Fisher showed in 1918 that if many genes affect a trait, random sampling of alleles produces a continuous, normally distributed phenotype. Height illustrates the extreme polygenicity typical of many complex traits: across all SNPs genome-wide, the median SNP is associated with an effect of 0.14 mm on height, about one tenth of the median effect of genome-wide significant SNPs (1.43 mm). Under simplifying assumptions the authors estimate that more than 100,000 SNPs have independent causal effects on height. They propose an omnigenic model as a hypothesis.

    Expert-authored, peer-reviewed overview, posted 8 June 2000, comprehensive update 29 July 2021. More than 70 polypeptides form the respiratory chain on the inner mitochondrial membrane. Mitochondrial DNA encodes 13 essential respiratory-chain subunits (seven of complex I, one of complex III, three of complex IV and two of complex V), two ribosomal RNAs (12S and 16S) and 22 transfer RNAs for intra-mitochondrial protein synthesis; the remaining respiratory-chain polypeptides and the proteins for respiratory-chain assembly, mitochondrial structure and mtDNA maintenance and expression are encoded by the nuclear genome. Each human cell contains thousands of copies of mtDNA; in heteroplasmy, mutated and wild-type mtDNA coexist, and the proportion of mutated mtDNA must exceed a critical threshold before a cell expresses a biochemical defect of the respiratory chain. mtDNA pathogenic variants are transmitted by maternal inheritance; offspring of males with an mtDNA pathogenic variant do not inherit it.

    Comment. Within a cell lineage, gene activity states are maintained over cell divisions; this cellular inheritance is attributed to regulatory feedback loops, chromatin modifications (DNA methylation and histone modifications) and long-lived non-coding RNAs. Chromatin is extensively reshaped during germ-cell differentiation and in totipotent cells after fertilisation. Transgenerational epigenetic inheritance in humans is a matter of controversial debate because genetic, ecological and cultural inheritance confound it; epidemiological links between grandparental food supply and grandchildren's health await independent replication; most families in which abnormal DNA methylation segregated with a rare disease proved to carry an underlying genetic variant; the excess cardiovascular and metabolic disease after prenatal exposure to the Dutch hunger winter is a direct consequence of exposure in utero, not germline transmission. The author concludes that the evidence is not (yet) conclusive.
