The c.364C>T (p.R122W) alteration is located in exon 1 (coding exon 1) of the FAM179B gene. This alteration results from a C to T substitution at nucleotide position 364, causing the arginine (R) at amino acid position 122 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
