Genes affected

WDR7 (HGNC:13490): (WD repeat domain 7) This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD) that may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. The encoded protein forms the beta subunit of rabconnectin-3 and binds directly with Rab3A GDP/GTP exchange protein and indirectly with Rab3A GDP/GTP activating protein; these proteins are regulators of Rab3 small G protein family members involved in control of the calcium-dependant exocytosis of neurotransmitters. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

WDR7-OT1 (HGNC:45131): (WDR7 overlapping transcript 1)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.79).
• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.0199 (3037/152286) while in subpopulation EAS AF = 0.0499 (258/5172). AF 95% confidence interval is 0.0449. There are 36 homozygotes in GnomAd4. There are 1423 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAd4 at 3037 AD gene.
