Collection Method: clinical testing

The c.332C>T (p.A111V) alteration is located in exon 3 (coding exon 3) of the TMEM196 gene. This alteration results from a C to T substitution at nucleotide position 332, causing the alanine (A) at amino acid position 111 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
