The c.674T>G (p.F225C) alteration is located in exon 6 (coding exon 6) of the PECR gene. This alteration results from a T to G substitution at nucleotide position 674, causing the phenylalanine (F) at amino acid position 225 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
