Genes affected

LAPTM4B (HGNC:13646): (lysosomal protein transmembrane 4 beta) Enables ceramide binding activity; enzyme binding activity; and phosphatidylinositol bisphosphate binding activity. Involved in several processes, including negative regulation of macromolecule metabolic process; regulation of lysosomal membrane permeability; and regulation of lysosome organization. Located in several cellular components, including endosome; lysosomal membrane; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
