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]

THSD7A-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesApr 13, 2023The THSD7A c.4775_4779dup5 variant is predicted to result in a frameshift and premature protein termination (p.Phe1594Profs*13). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0065% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/7-11418718-A-ACCAGG). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
