The c.2746C>T (p.R916C) alteration is located in exon 15 (coding exon 15) of the FAM184B gene. This alteration results from a C to T substitution at nucleotide position 2746, causing the arginine (R) at amino acid position 916 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
