The c.322A>G (p.T108A) alteration is located in exon 4 (coding exon 4) of the TMEM147 gene. This alteration results from a A to G substitution at nucleotide position 322, causing the threonine (T) at amino acid position 108 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
