The c.326C>G (p.T109S) alteration is located in exon 2 (coding exon 2) of the TMEM236 gene. This alteration results from a C to G substitution at nucleotide position 326, causing the threonine (T) at amino acid position 109 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
