Genes affected

WDR27 (HGNC:21248): (WD repeat domain 27) This gene encodes a protein with multiple WD repeats. Proteins with these repeats may form scaffolds for protein-protein interaction and play key roles in cell signalling. Alternative splicing results in multiple transcript variants, but the full-length structure of some of these variants cannot be determined. [provided by RefSeq, Nov 2015]

Collection Method: clinical testing

The c.2182G>C (p.E728Q) alteration is located in exon 21 (coding exon 20) of the WDR27 gene. This alteration results from a G to C substitution at nucleotide position 2182, causing the glutamic acid (E) at amino acid position 728 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
