Genes affected

THSD7A (HGNC:22207): (thrombospondin type 1 domain containing 7A) The protein encoded by this gene is found almost exclusively in endothelial cells from placenta and umbilical cord. The encoded protein appears to interact with alpha(V)beta(3) integrin and paxillin to inhibit endothelial cell migration and tube formation. This protein may be involved in cytoskeletal organization. Variations in this gene may be associated with low bone mineral density in osteoporosis. [provided by RefSeq, Aug 2010]

The c.4814A>C (p.K1605T) alteration is located in exon 27 (coding exon 27) of the THSD7A gene. This alteration results from a A to C substitution at nucleotide position 4814, causing the lysine (K) at amino acid position 1605 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
