Genes affected

WDR17 (HGNC:16661): (WD repeat domain 17) This gene encodes a WD repeat-containing protein. It is abundantly expressed in retina and testis, and is thought to be a candidate gene for retinal disease. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Nov 2009]

The c.313G>A (p.D105N) alteration is located in exon 4 (coding exon 3) of the WDR17 gene. This alteration results from a G to A substitution at nucleotide position 313, causing the aspartic acid (D) at amino acid position 105 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
