Genes affected
SPOCK3 (HGNC:13565): (SPARC (osteonectin), cwcv and kazal like domains proteoglycan 3) This gene encodes a member of a novel family of calcium-binding proteoglycan proteins that contain thyroglobulin type-1 and Kazal-like domains. The encoded protein and may play a role in adult T-cell leukemia by inhibiting the activity of membrane-type matrix metalloproteinases. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Oct 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2022The c.647G>C (p.W216S) alteration is located in exon 8 (coding exon 7) of the SPOCK3 gene. This alteration results from a G to C substitution at nucleotide position 647, causing the tryptophan (W) at amino acid position 216 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
