Genes affected

FRMD4B (HGNC:24886): (FERM domain containing 4B) This gene encodes a GRP1-binding protein which contains a FERM protein interaction domain as well as two coiled coil domains. This protein may play a role as a scaffolding protein. [provided by RefSeq, Mar 2014]

The c.3038A>T (p.D1013V) alteration is located in exon 23 (coding exon 23) of the FRMD4B gene. This alteration results from a A to T substitution at nucleotide position 3038, causing the aspartic acid (D) at amino acid position 1013 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
