The c.1037T>G (p.F346C) alteration is located in exon 13 (coding exon 13) of the ERGIC3 gene. This alteration results from a T to G substitution at nucleotide position 1037, causing the phenylalanine (F) at amino acid position 346 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
