The c.286C>A (p.L96M) alteration is located in exon 3 (coding exon 3) of the ESRP1 gene. This alteration results from a C to A substitution at nucleotide position 286, causing the leucine (L) at amino acid position 96 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
