Genes affected
SPOCK2 (HGNC:13564): (SPARC (osteonectin), cwcv and kazal like domains proteoglycan 2) This gene encodes a protein which binds with glycosaminoglycans to form part of the extracellular matrix. The protein contains thyroglobulin type-1, follistatin-like, and calcium-binding domains, and has glycosaminoglycan attachment sites in the acidic C-terminal region. Three alternatively spliced transcript variants that encode different protein isoforms have been described for this gene. [provided by RefSeq, Oct 2011]

The c.1103C>T (p.T368M) alteration is located in exon 11 (coding exon 10) of the SPOCK2 gene. This alteration results from a C to T substitution at nucleotide position 1103, causing the threonine (T) at amino acid position 368 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
