Genes affected
FLOT1 (HGNC:3757): (flotillin 1) This gene encodes an protein that localizes to the caveolae, which are small domains on the inner cell membranes. This protein plays a role in vesicle trafficking and cell morphology. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 03, 2022The c.676G>A (p.E226K) alteration is located in exon 8 (coding exon 7) of the FLOT1 gene. This alteration results from a G to A substitution at nucleotide position 676, causing the glutamic acid (E) at amino acid position 226 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
