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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2024The c.109G>T (p.A37S) alteration is located in exon 2 (coding exon 1) of the VWC2 gene. This alteration results from a G to T substitution at nucleotide position 109, causing the alanine (A) at amino acid position 37 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
