Genes affected

ADAMTSL1 (HGNC:14632): (ADAMTS like 1) This gene encodes a secreted protein and member of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motif) family. This protein lacks the metalloproteinase and disintegrin-like domains, which are typical of the ADAMTS family, but contains other ADAMTS domains, including the thrombospondin type 1 motif. This protein may have important functions in the extracellular matrix. Alternative splicing results in multiple transcript variants encoding distinct proteins. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.217T>C (p.Y73H) alteration is located in exon 3 (coding exon 3) of the ADAMTSL1 gene. This alteration results from a T to C substitution at nucleotide position 217, causing the tyrosine (Y) at amino acid position 73 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
