(A) The c.1976A>T (p.Gln659Leu) mutation is shown in a schematic of the gene structure. (B) (Q) Glutamine at position 659 is highly conserved in CHAT in various species (the box marks the amino acid of interest). (C) Homology models for CHAT protein generated using the crystal structures of CHAT protein (PDB accession code: 2FY4) as the template. (D) Cartoon structure representation of the subtle changes (Gln-to-Leu) at position 659. The green cartoon represents the wild-type protein, and the purple cartoon represents the mutant protein. Yellow dots represent polar contacts.
