Collection Method: clinical testing

The c.493A>G (p.M165V) alteration is located in exon 4 (coding exon 4) of the THEM5 gene. This alteration results from a A to G substitution at nucleotide position 493, causing the methionine (M) at amino acid position 165 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
