The c.797C>T (p.A266V) alteration is located in exon 2 (coding exon 2) of the EFCC1 gene. This alteration results from a C to T substitution at nucleotide position 797, causing the alanine (A) at amino acid position 266 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
