Genes affected

AP5Z1 (HGNC:22197): (adaptor related protein complex 5 subunit zeta 1) This gene was identified by genome-wide screen for genes involved in homologous recombination DNA double-strand break repair (HR-DSBR). The encoded protein was found in a complex with other proteins that have a role in HR-DSBR. Knockdown of this gene reduced homologous recombination, and mutations in this gene were found in patients with spastic paraplegia. It was concluded that this gene likely encodes a helicase (PMID:20613862). [provided by RefSeq, Jan 2011]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000919 (140/152304) while in subpopulation NFE AF = 0.00173 (118/68014). AF 95% confidence interval is 0.00148. There are 1 homozygotes in GnomAd4. There are 54 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
