The c.616C>T (p.R206W) alteration is located in exon 6 (coding exon 4) of the FAM114A1 gene. This alteration results from a C to T substitution at nucleotide position 616, causing the arginine (R) at amino acid position 206 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
