Genes affected
SOSTDC1 (HGNC:21748): (sclerostin domain containing 1) This gene is a member of the sclerostin family and encodes an N-glycosylated, secreted protein with a C-terminal cystine knot-like domain. This protein functions as a bone morphogenetic protein (BMP) antagonist. Specifically, it directly associates with BMPs, prohibiting them from binding their receptors, thereby regulating BMP signaling during cellular proliferation, differentiation, and programmed cell death. [provided by RefSeq, Jul 2008]
CRPPA (HGNC:37276): (CDP-L-ribitol pyrophosphorylase A) This gene encodes a 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase-like protein. Mutations in this gene are the cause of Walker-Warburg syndrome. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2012]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.263A>G (p.Q88R) alteration is located in exon 2 (coding exon 2) of the SOSTDC1 gene. This alteration results from a A to G substitution at nucleotide position 263, causing the glutamine (Q) at amino acid position 88 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
