ADAMTSL1

Chr 9

ADAMTS like 1

Also known as: ADAMTSL-1, ADAMTSR1, C9orf94, PUNCTIN

The protein is a secreted extracellular matrix component that contains thrombospondin motifs but lacks the metalloproteinase domains typical of other ADAMTS family members. Mutations cause geleophysic dysplasia, a rare skeletal dysplasia characterized by short stature, joint contractures, distinctive facial features, and cardiac valve abnormalities, with autosomal recessive inheritance. The gene is highly constrained against loss-of-function variants (LOEUF 0.531), indicating that complete loss of protein function is likely deleterious.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
