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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.2387G>C (p.S796T) 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 2387, causing the serine (S) at amino acid position 796 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
