The c.368G>A (p.G123E) alteration is located in exon 3 (coding exon 3) of the PECR gene. This alteration results from a G to A substitution at nucleotide position 368, causing the glycine (G) at amino acid position 123 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
