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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2023The c.859C>T (p.R287C) alteration is located in exon 8 (coding exon 8) of the FLOT2 gene. This alteration results from a C to T substitution at nucleotide position 859, causing the arginine (R) at amino acid position 287 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
