The c.1864G>A (p.A622T) alteration is located in exon 12 (coding exon 10) of the ATG9A gene. This alteration results from a G to A substitution at nucleotide position 1864, causing the alanine (A) at amino acid position 622 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
