Genes affected

CYP2D7 (HGNC:2624): (cytochrome P450 family 2 subfamily D member 7 (gene/pseudogene)) This gene is a member of the cytochrome P450 gene superfamily. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This gene is a segregating pseudogene, where some individuals may have an allele that encodes a functional enzyme, while other individuals have an allele encoding a protein that is predicted to be non-functional. In this case, the functional allele is thought to be rare. This locus is part of a cluster of cytochrome P450 genes on chromosome 22. [provided by RefSeq, Jan 2017]

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.61).
• BP6: Variant 22-42141910-T-G is Benign according to our data. Variant chr22-42141910-T-G is described in ClinVar as Likely_benign. ClinVar VariationId is 2653243.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.00225 (3276/1458314) while in subpopulation MID AF = 0.0202 (116/5754). AF 95% confidence interval is 0.0172. There are 31 homozygotes in GnomAdExome4. There are 1675 alleles in the male GnomAdExome4 subpopulation. Median coverage is 34. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 4 AR gene
