Collection Method: clinical testing

The c.505C>T (p.R169W) alteration is located in exon 3 (coding exon 2) of the TMEM136 gene. This alteration results from a C to T substitution at nucleotide position 505, causing the arginine (R) at amino acid position 169 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
