The c.2597G>T (p.C866F) alteration is located in exon 15 (coding exon 14) of the EPB41L2 gene. This alteration results from a G to T substitution at nucleotide position 2597, causing the cysteine (C) at amino acid position 866 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
