Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to T transversion at position 1834 of the Abca8a transcript in exon 13 of 39 total exons. Multiple transcripts of the Abca8a gene are displayed on Ensembl and Vega. The mutated nucleotide causes an isoleucine to phenylalanine substitution at amino acid 585 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

 

 

Protein Function and Prediction

The Abca8a gene encodes a 1620 amino acid member of the ATP binding cassette (ABC) transporter superfamily. The protein is predicted to be an ATP-dependent lipophilic drug transporter, and contains 15 transmembrane domains as well as two ABC transporter domains at residues 478-713 and 1284-1517 (Uniprot Q8K442).

The I585F change occurs in the first ABC transporter domain, and is predicted to be probably damaging by the PolyPhen program.
