Genes affected
THBS2 (HGNC:11786): (thrombospondin 2) The protein encoded by this gene belongs to the thrombospondin family. It is a disulfide-linked homotrimeric glycoprotein that mediates cell-to-cell and cell-to-matrix interactions. This protein has been shown to function as a potent inhibitor of tumor growth and angiogenesis. Studies of the mouse counterpart suggest that this protein may modulate the cell surface properties of mesenchymal cells and be involved in cell adhesion and migration. [provided by RefSeq, Jul 2008]
THBS2-AS1 (HGNC:56059): (THBS2 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2023The c.3164C>T (p.T1055M) alteration is located in exon 20 (coding exon 18) of the THBS2 gene. This alteration results from a C to T substitution at nucleotide position 3164, causing the threonine (T) at amino acid position 1055 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
