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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 26, 2024The c.298C>T (p.L100F) alteration is located in exon 1 (coding exon 1) of the SDPR gene. This alteration results from a C to T substitution at nucleotide position 298, causing the leucine (L) at amino acid position 100 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
