Genes affected

GREM2 (HGNC:17655): (gremlin 2, DAN family BMP antagonist) This gene encodes a member of the BMP (bone morphogenic protein) antagonist family. Like BMPs, BMP antagonists contain cystine knots and typically form homo- and heterodimers. The CAN (cerberus and dan) subfamily of BMP antagonists, to which this gene belongs, is characterized by a C-terminal cystine knot with an eight-membered ring. The antagonistic effect of the secreted glycosylated protein encoded by this gene is likely due to its direct binding to BMP proteins. As an antagonist of BMP, this gene may play a role in regulating organogenesis, body patterning, and tissue differentiation. [provided by RefSeq, Jul 2008]

The c.328G>C (p.V110L) alteration is located in exon 2 (coding exon 1) of the GREM2 gene. This alteration results from a G to C substitution at nucleotide position 328, causing the valine (V) at amino acid position 110 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
