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

May 05, 2023

The c.2128G>C (p.D710H) alteration is located in exon 18 (coding exon 18) of the THBS3 gene. This alteration results from a G to C substitution at nucleotide position 2128, causing the aspartic acid (D) at amino acid position 710 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
