Summary
This gene is one of the contiguous genes at 7q11.23 commonly deleted in Williams syndrome, a multisystem developmental disorder. This gene consists of at least 14 exons, and its alternative splicing generates 3 transcript variants, all encoding the same protein. [provided by RefSeq, Jul 2008]
Annotation information
Note: LAT2 (Gene ID: 7462) and SLC7A8 (Gene ID: 23428) share the LAT2 symbol/alias in common. LAT2 is sometimes used as an alternative name for solute carrier family 7 member 8 (SLC7A8), which can be confused with the official symbol for linker for activation of T cells family member 2 (LAT2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
