The c.1345A>G (p.T449A) alteration is located in exon 8 (coding exon 7) of the TMEM117 gene. This alteration results from a A to G substitution at nucleotide position 1345, causing the threonine (T) at amino acid position 449 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
