Genes affected
NUDT15 (HGNC:23063): (nudix hydrolase 15) This gene encodes an enzyme that belongs to the Nudix hydrolase superfamily. Members of this superfamily catalyze the hydrolysis of nucleoside diphosphates, including substrates like 8-oxo-dGTP, which are a result of oxidative damage, and can induce base mispairing during DNA replication, causing transversions. The encoded enzyme is a negative regulator of thiopurine activation and toxicity. Mutations in this gene result in poor metabolism of thiopurines, and are associated with thiopurine-induced early leukopenia. Multiple pseudogenes of this gene have been identified.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.006871134).
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.00222 (338/152226) while in subpopulation AMR AF= 0.0205 (313/15286). AF 95% confidence interval is 0.0186. There are 5 homozygotes in gnomad4. There are 197 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAd4 at 338 AD gene.
