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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2023The c.2344G>T (p.D782Y) alteration is located in exon 5 (coding exon 4) of the THSD1 gene. This alteration results from a G to T substitution at nucleotide position 2344, causing the aspartic acid (D) at amino acid position 782 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
