The c.544C>T (p.R182C) alteration is located in exon 6 (coding exon 6) of the PIFO gene. This alteration results from a C to T substitution at nucleotide position 544, causing the arginine (R) at amino acid position 182 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
