Genes affected

FLOT2 (HGNC:3758): (flotillin 2) Caveolae are small domains on the inner cell membrane involved in vesicular trafficking and signal transduction. This gene encodes a caveolae-associated, integral membrane protein, which is thought to function in neuronal signaling. [provided by RefSeq, Jul 2008]

The c.632A>G (p.K211R) alteration is located in exon 7 (coding exon 7) of the FLOT2 gene. This alteration results from a A to G substitution at nucleotide position 632, causing the lysine (K) at amino acid position 211 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
