Genes affected

CAVIN2 (HGNC:10690): (caveolae associated protein 2) This gene encodes a calcium-independent phospholipid-binding protein whose expression increases in serum-starved cells. This protein is a substrate for protein kinase C (PKC) phosphorylation and recruits polymerase I and transcript release factor (PTRF) to caveolae. Removal of this protein causes caveolae loss and its over-expression results in caveolae deformation and membrane tubulation.[provided by RefSeq, Sep 2009]

Ambry Genetics

Jan 09, 2024

The c.1252G>A (p.V418M) alteration is located in exon 2 (coding exon 2) of the SDPR gene. This alteration results from a G to A substitution at nucleotide position 1252, causing the valine (V) at amino acid position 418 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
