Genes affected

SVBP (HGNC:29204): (small vasohibin binding protein) Enables microtubule binding activity. Involved in axon development; proteolysis; and regulation of metallopeptidase activity. Acts upstream of or within negative regulation of endothelial cell migration; negative regulation of protein ubiquitination; and protein secretion. Located in apical part of cell.

Ambry Genetics

Jun 24, 2022

The c.91C>G (p.L31V) alteration is located in exon 2 (coding exon 1) of the SVBP gene. This alteration results from a C to G substitution at nucleotide position 91, causing the leucine (L) at amino acid position 31 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
