The c.116C>G (p.A39G) alteration is located in exon 1 (coding exon 1) of the TMEM261 gene. This alteration results from a C to G substitution at nucleotide position 116, causing the alanine (A) at amino acid position 39 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
