The c.391A>C (p.M131L) alteration is located in exon 4 (coding exon 4) of the EAF2 gene. This alteration results from a A to C substitution at nucleotide position 391, causing the methionine (M) at amino acid position 131 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
