Genes affected

LAPTM4A (HGNC:6924): (lysosomal protein transmembrane 4 alpha) This gene encodes a protein that has four predicted transmembrane domains. The function of this gene has not yet been determined; however, studies in the mouse homolog suggest a role in the transport of small molecules across endosomal and lysosomal membranes.
