Genes affected
SLC7A6 (HGNC:11064): (solute carrier family 7 member 6) Enables basic amino acid transmembrane transporter activity. Involved in basic amino acid transmembrane transport and ornithine transport. Located in intracellular membrane-bounded organelle and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
SLC7A6OS (HGNC:25807): (solute carrier family 7 member 6 opposite strand) Predicted to be involved in developmental process. Predicted to act upstream of or within hematopoietic progenitor cell differentiation. Predicted to be located in cytoplasm and nucleus. Implicated in progressive myoclonus epilepsy. [provided by Alliance of Genome Resources, Apr 2022]
