Collection Method: clinical testing

The c.236C>G (p.T79R) alteration is located in exon 4 (coding exon 4) of the TMEM141 gene. This alteration results from a C to G substitution at nucleotide position 236, causing the threonine (T) at amino acid position 79 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
