Genes affected
XPNPEP3 (HGNC:28052): (X-prolyl aminopeptidase 3) The protein encoded by this gene belongs to the family of X-pro-aminopeptidases that utilize a metal cofactor, and remove the N-terminal amino acid from peptides with a proline residue in the penultimate position. This protein has been shown to localize to the mitochondria of renal cells, and have a role in ciliary function. Mutations in this gene are associated with nephronophthisis-like nephropathy-1. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene, however, expression of some of these isoforms in vivo is not known.[provided by RefSeq, Mar 2011]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-1.0).
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000696 (106/152336) while in subpopulation AMR AF= 0.00098 (15/15308). AF 95% confidence interval is 0.000703. There are 0 homozygotes in gnomad4. There are 44 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
