Genes affected
WDR26 (HGNC:21208): (WD repeat domain 26) 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), which 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. Two transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 5 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), WDR26. . Gene score misZ: 3.5843 (greater than the threshold 3.09). Trascript score misZ: 3.3396 (greater than threshold 3.09). The gene has 13 curated pathogenic missense variants (we use a threshold of 10). The gene has 6 curated benign missense variants. GenCC has associacion of the gene with Skraban-Deardorff syndrome.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.86
