The c.517A>G (p.T173A) alteration is located in exon 5 (coding exon 4) of the TMEM39A gene. This alteration results from a A to G substitution at nucleotide position 517, causing the threonine (T) at amino acid position 173 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
