The c.569C>T (p.A190V) alteration is located in exon 3 (coding exon 3) of the EPHA6 gene. This alteration results from a C to T substitution at nucleotide position 569, causing the alanine (A) at amino acid position 190 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
