Genes affected

NT5C3B (HGNC:28300): (5'-nucleotidase, cytosolic IIIB) Predicted to enable 5'-nucleotidase activity. Predicted to be involved in exonucleolytic catabolism of deadenylated mRNA. Predicted to be located in cytosol. Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

KLHL10 (HGNC:18829): (kelch like family member 10) The protein encoded by this gene belongs to the kelch repeat-containing family, and contains an N-terminal BTB/POZ domain a BACK domain and six C-terminal kelch repeats. Kelch domains are thought to form a four stranded beta-sheet blade structure that can fold into a beta-propeller domain when multiple kelch repeats are found together. Mutations in this gene have been associated with oligozoospermia in some infertile males. [provided by RefSeq, Jul 2016]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.831 is higher than 0.05.
