Variant summary

Our verdict is Pathogenic. The variant received 13 ACMG points: 13P and 0B. PS3PP3PP5_Very_Strong

The NM_000110.4(DPYD):​c.1475C>T​(p.Ser492Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000266 in 1,613,686 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV001623227: "The variant resulted in nearly absent enzyme activity in homozygous patient cells and substantially reduced activity (~18% of wild type) when expressed in an isogenic cell line" (PMID:24648345, 11988088, 24590654, 31745289, 32707991, 32899374, 28481884, 12912951, 27454530, 17046731, 33083013)." and additional evidence is available in ClinVar.

Genes affected
DPYD (HGNC:3012): (dihydropyrimidine dehydrogenase) The protein encoded by this gene is a pyrimidine catabolic enzyme and the initial and rate-limiting factor in the pathway of uracil and thymidine catabolism. Mutations in this gene result in dihydropyrimidine dehydrogenase deficiency, an error in pyrimidine metabolism associated with thymine-uraciluria and an increased risk of toxicity in cancer patients receiving 5-fluorouracil chemotherapy. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009]
