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 08, 2024The c.2210A>G (p.K737R) alteration is located in exon 5 (coding exon 4) of the THSD1 gene. This alteration results from a A to G substitution at nucleotide position 2210, causing the lysine (K) at amino acid position 737 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
