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]

The c.1058A>G (p.H353R) alteration is located in exon 11 (coding exon 10) of the SPOCK3 gene. This alteration results from a A to G substitution at nucleotide position 1058, causing the histidine (H) at amino acid position 353 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
