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.2442G>C (p.E814D) alteration is located in exon 21 (coding exon 21) of the FRMD4B gene. This alteration results from a G to C substitution at nucleotide position 2442, causing the glutamic acid (E) at amino acid position 814 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
