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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 30, 2023The c.421G>A (p.V141M) alteration is located in exon 5 (coding exon 4) of the SPOCK1 gene. This alteration results from a G to A substitution at nucleotide position 421, causing the valine (V) at amino acid position 141 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
