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]
THBS3-AS1 (HGNC:40582): (THBS3 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2024The c.2615G>A (p.R872Q) alteration is located in exon 21 (coding exon 21) of the THBS3 gene. This alteration results from a G to A substitution at nucleotide position 2615, causing the arginine (R) at amino acid position 872 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
