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]

The c.351C>A (p.N117K) alteration is located in exon 4 (coding exon 4) of the ADAMTSL1 gene. This alteration results from a C to A substitution at nucleotide position 351, causing the asparagine (N) at amino acid position 117 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
