Collection Method:clinical testing

The c.26A>T (p.N9I) alteration is located in exon 2 (coding exon 1) of the TMEM219 gene. This alteration results from a A to T substitution at nucleotide position 26, causing the asparagine (N) at amino acid position 9 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
