The c.329A>G (p.Y110C) alteration is located in exon 2 (coding exon 1) of the MAP1LC3B2 gene. This alteration results from a A to G substitution at nucleotide position 329, causing the tyrosine (Y) at amino acid position 110 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
