Dec 02, 2022

The c.508C>T (p.R170C) alteration is located in exon 3 (coding exon 3) of the PPFIA4 gene. This alteration results from a C to T substitution at nucleotide position 508, causing the arginine (R) at amino acid position 170 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
