Collection Method: clinical testing

The c.307C>T (p.R103C) alteration is located in exon 3 (coding exon 3) of the TMEM134 gene. This alteration results from a C to T substitution at nucleotide position 307, causing the arginine (R) at amino acid position 103 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
