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 GeneticsDec 13, 2023The c.2591G>A (p.R864Q) alteration is located in exon 21 (coding exon 21) of the FRMD4B gene. This alteration results from a G to A substitution at nucleotide position 2591, causing the arginine (R) at amino acid position 864 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
