The c.2194C>T (p.R732C) alteration is located in exon 14 (coding exon 12) of the ATG9A gene. This alteration results from a C to T substitution at nucleotide position 2194, causing the arginine (R) at amino acid position 732 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
