Genes affected

SPARC (HGNC:11219): (secreted protein acidic and cysteine rich) This gene encodes a cysteine-rich acidic matrix-associated protein. The encoded protein is required for the collagen in bone to become calcified but is also involved in extracellular matrix synthesis and promotion of changes to cell shape. The gene product has been associated with tumor suppression but has also been correlated with metastasis based on changes to cell shape which can promote tumor cell invasion. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2015]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with SPARC-related conditions. This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 301 of the SPARC protein (p.Leu301Val). This variant is present in population databases (rs764270465, gnomAD 0.003%). -
