The c.62C>G (p.A21G) 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 62, causing the alanine (A) at amino acid position 21 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
