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 GeneticsJun 02, 2023The c.942C>A (p.D314E) alteration is located in exon 10 (coding exon 9) of the SPOCK3 gene. This alteration results from a C to A substitution at nucleotide position 942, causing the aspartic acid (D) at amino acid position 314 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
