The c.172C>T (p.R58C) alteration is located in exon 3 (coding exon 3) of the MT1B gene. This alteration results from a C to T substitution at nucleotide position 172, causing the arginine (R) at amino acid position 58 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
