Collection Method: clinical testing

The c.316C>T (p.R106W) alteration is located in exon 5 (coding exon 4) of the TMEM104 gene. This alteration results from a C to T substitution at nucleotide position 316, causing the arginine (R) at amino acid position 106 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
