The c.5506C>T (p.R1836W) alteration is located in exon 40 (coding exon 40) of the ATG2A gene. This alteration results from a C to T substitution at nucleotide position 5506, causing the arginine (R) at amino acid position 1836 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
