Genes affected

RSPO3 (HGNC:20866): (R-spondin 3) This gene belongs to the R-spondin family. The encoded protein plays a role in the regulation of Wnt (wingless-type MMTV integration site family)/beta-catenin and Wnt/planar cell polarity (PCP) signaling pathways, which are involved in development, cell growth and disease pathogenesis. Genome-wide association studies suggest a correlation of this gene with bone mineral density and risk of fracture. This gene may be involved in tumor development. [provided by RefSeq, Jul 2013]

The c.103C>A (p.P35T) alteration is located in exon 2 (coding exon 2) of the RSPO3 gene. This alteration results from a C to A substitution at nucleotide position 103, causing the proline (P) at amino acid position 35 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
