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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -6 ACMG points.

PP3
Multiple lines of computational evidence support a deleterious effect 7: BayesDel_noAF, Eigen, M_CAP, phyloP100way_vertebrate, PROVEAN, REVEL, REVEL [when AlphaMissense, max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]
BP4
Computational evidence support a benign effect (MetaRNN=0.13372508).
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00328 (499/152236) while in subpopulation NFE AF = 0.00605 (411/67978). AF 95% confidence interval is 0.00556. There are 3 homozygotes in GnomAd4. There are 211 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High Homozygotes in GnomAd4 at 3 AR gene
