Genes affected

FREM3 (HGNC:25172): (FRAS1 related extracellular matrix 3) This gene encodes an integral membrane protein containing numerous CSPG (chondroitin sulfate proteoglycan element) repeats and Calx-beta domains. The protein belongs to the family of FRAS1/FREM extracellular matrix proteins and may play a role cell adhesion. [provided by RefSeq, Feb 2017]

The c.5242A>G (p.K1748E) alteration is located in exon 2 (coding exon 2) of the FREM3 gene. This alteration results from a A to G substitution at nucleotide position 5242, causing the lysine (K) at amino acid position 1748 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
