Genes affected

SCYL3 (HGNC:19285): (SCY1 like pseudokinase 3) This gene encodes a protein with a kinase domain and four HEAT repeats. The encoded protein interacts with the C-terminal domain of ezrin, an ERM protein, and may play a role in cell adhesion and migration. Alternative splicing results in multiple transcript variants encoding multiple isoforms. [provided by RefSeq, Jun 2012]

The c.1967G>A (p.G656E) alteration is located in exon 13 (coding exon 12) of the SCYL3 gene. This alteration results from a G to A substitution at nucleotide position 1967, causing the glycine (G) at amino acid position 656 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
