Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_000765.5(CYP3A7):c.1313G>T(p.Gly438Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,716 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G438E) has been classified as Uncertain significance.

Genes affected

CYP3A7 (HGNC:2640): (cytochrome P450 family 3 subfamily A member 7) This gene encodes a member of the cytochrome P450 superfamily of enzymes, which participate in drug metabolism and the synthesis of cholesterol, steroids and other lipids. This enzyme hydroxylates testosterone and dehydroepiandrosterone 3-sulphate, which is involved in the formation of estriol during pregnancy. This gene is part of a cluster of related genes on chromosome 7q21.1. Naturally-occurring readthrough transcription occurs between this gene and the downstream CYP3A51P pseudogene and is represented by GeneID:100861540. [provided by RefSeq, Jan 2015]

CYP3A7 links:

CYP3A7-CYP3A51P (HGNC:51504): (CYP3A7-CYP3A51P readthrough) This locus represents readthrough transcription between the neighboring CYP3A7 (cytochrome P450, family 3, subfamily A, polypeptide 7) and CYP3A51P (cytochrome P450, family 3, subfamily A, polypeptide 51, pseudogene) genes, which are members of the CYP3A gene cluster on chromosome 7. The downstream pseudogene is not known to be independently transcribed. The readthrough transcript includes CYP3A7 exons 1-13 and exons 2 and 13 of the pseudogene. It encodes a CYP3A isoform with a novel C-terminus. This isoform is only expressed in alleles containing a T nucleotide at the -6 position of a splice acceptor in the pseudogene, which enables correct splicing of the upstream CYP3A7 exons to the pseudogene exons. It should be noted that the reference genome sequence represents the CYP3A7_39256 T->A allele, and thus this haplotype is unlikely to produce the readthrough transcript. [provided by RefSeq, Jan 2015]

CYP3A7-CYP3A51P links:

ZSCAN25 (HGNC:21961): (zinc finger and SCAN domain containing 25) This gene encodes a protein that bears some similarity to zinc finger proteins, which are involved in DNA binding and protein-protein interactions. Multiple alternatively spliced transcript variants have been identified, but the full-length nature for most of them has not been determined. [provided by RefSeq, Jul 2008]
