Genes affected

VWC2 (HGNC:30200): (von Willebrand factor C domain containing 2) This gene encodes a secreted bone morphogenic protein antagonist. The encoded protein is possibly involved in neural function and development and may have a role in cell adhesion.[provided by RefSeq, Oct 2009]

Dec 18, 2023

The c.410C>G (p.P137R) alteration is located in exon 2 (coding exon 1) of the VWC2 gene. This alteration results from a C to G substitution at nucleotide position 410, causing the proline (P) at amino acid position 137 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
