Collection Method: clinical testing

The c.422C>G (p.S141C) alteration is located in exon 3 (coding exon 3) of the MOV10L1 gene. This alteration results from a C to G substitution at nucleotide position 422, causing the serine (S) at amino acid position 141 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
