Genes affected

THBS3 (HGNC:11787): (thrombospondin 3) The protein encoded by this gene belongs to the thrombospondin family. Thrombospondin family members are adhesive glycoproteins that mediate cell-to-cell and cell-to-matrix interactions. This protein forms a pentameric molecule linked by a single disulfide bond. This gene shares a common promoter with metaxin 1. Alternate splicing results in coding and non-coding transcript variants. [provided by RefSeq, Nov 2011]

Ambry Genetics

Sep 07, 2022

The c.2083G>A (p.V695I) alteration is located in exon 18 (coding exon 18) of the THBS3 gene. This alteration results from a G to A substitution at nucleotide position 2083, causing the valine (V) at amino acid position 695 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
