The c.649C>T (p.R217W) alteration is located in exon 2 (coding exon 2) of the FAM83F gene. This alteration results from a C to T substitution at nucleotide position 649, causing the arginine (R) at amino acid position 217 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
