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.838A>G (p.K280E) alteration is located in exon 8 (coding exon 8) of the FLOT2 gene. This alteration results from a A to G substitution at nucleotide position 838, causing the lysine (K) at amino acid position 280 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
