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]

The c.350C>T (p.T117I) alteration is located in exon 2 (coding exon 1) of the VWC2 gene. This alteration results from a C to T substitution at nucleotide position 350, causing the threonine (T) at amino acid position 117 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
