Genes affected

SPOCK1 (HGNC:11251): (SPARC (osteonectin), cwcv and kazal like domains proteoglycan 1) This gene encodes the protein core of a seminal plasma proteoglycan containing chondroitin- and heparan-sulfate chains. The protein's function is unknown, although similarity to thyropin-type cysteine protease-inhibitors suggests its function may be related to protease inhibition. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jul 11, 2023

The c.721A>G (p.I241V) alteration is located in exon 8 (coding exon 7) of the SPOCK1 gene. This alteration results from a A to G substitution at nucleotide position 721, causing the isoleucine (I) at amino acid position 241 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
