Collection Method: clinical testing

The c.119C>T (p.A40V) alteration is located in exon 3 (coding exon 2) of the TMUB2 gene. This alteration results from a C to T substitution at nucleotide position 119, causing the alanine (A) at amino acid position 40 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
