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]

Ambry Genetics

May 14, 2024

The c.2682A>C (p.L894F) alteration is located in exon 21 (coding exon 21) of the FRMD4B gene. This alteration results from a A to C substitution at nucleotide position 2682, causing the leucine (L) at amino acid position 894 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
