Genes affected

THSD1 (HGNC:17754): (thrombospondin type 1 domain containing 1) The protein encoded by this gene contains a type 1 thrombospondin domain, which is found in a number of proteins involved in the complement pathway, as well as in extracellular matrix proteins. Alternatively spliced transcript variants encoding different isoforms have been observed for this gene. [provided by RefSeq, Jan 2009]

The THSD1 c.2237G>A variant is predicted to result in the amino acid substitution p.Gly746Glu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.010% of alleles in individuals of Ashkenazi Jewish descent in gnomAD (http://gnomad.broadinstitute.org/variant/13-52951868-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
