The c.2578G>A (p.V860I) alteration is located in exon 25 (coding exon 25) of the EPB41L4B gene. This alteration results from a G to A substitution at nucleotide position 2578, causing the valine (V) at amino acid position 860 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
