Genes affected
WDR45 (HGNC:28912): (WD repeat domain 45) 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. This gene has a pseudogene at chromosome 4q31.3. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene, but the biological validity and full-length nature of some variants have not been determined.

WDR45 NM_007075.3 exon 11 p.Tyr291= (c.873C>T): This variant has not been reported in the literature but is present in 3/12865 East Asian alleles, including 2 hemizygotes in the Genome Aggregation Database (http://gnomad.broadinstitute.org/rs782557596). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. Of note, this variant is a silent variant and does not change the amino acid, reducing the probability that this variant is disease causing. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

Inborn genetic diseases Benign:1
Dec 15, 2017
Ambry Genetics
Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
