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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.628G>A (p.A210T) alteration is located in exon 8 (coding exon 7) of the SPOCK3 gene. This alteration results from a G to A substitution at nucleotide position 628, causing the alanine (A) at amino acid position 210 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
