Amino acid transporter responsible for LPI

With this gene mutated, lysinuric protein intolerance occurs. The gene codes for an amino acid transporter.

Gene Structure

The gene SLC7A7, formerly known as y(+)LAT1, is located on chromosome 14 (14q11.2), spans about 46kb, and consists of 10 exons, 9 of which are translated.
