The c.239T>C (p.V80A) alteration is located in exon 2 (coding exon 2) of the MOV10L1 gene. This alteration results from a T to C substitution at nucleotide position 239, causing the valine (V) at amino acid position 80 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
