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: Benign. The variant received -9 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.8).
BP6
Variant 7-4781759-C-T is Benign according to our data. Variant chr7-4781759-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 360307.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00209 (318/152334) while in subpopulation AFR AF = 0.00717 (298/41580). AF 95% confidence interval is 0.0065. There are 1 homozygotes in GnomAd4. There are 134 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
