Genes affected

LAMP2 (HGNC:6501): (lysosomal associated membrane protein 2) The protein encoded by this gene is a member of a family of membrane glycoproteins. This glycoprotein provides selectins with carbohydrate ligands. It may play a role in tumor cell metastasis. It may also function in the protection, maintenance, and adhesion of the lysosome. Alternative splicing of this gene results in multiple transcript variants encoding distinct proteins. [provided by RefSeq, Jul 2008]

Benign:2

Benign, criteria provided, single submitter	clinical testing	GeneDx	May 15, 2017	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
Likely benign, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Nov 21, 2013	13C>T in the 3' UTR of LAMP2: This variant is not expected to have clinical sig nificance because it is not located within the splice consensus sequence. It ha s been identified in 1/6728 European American chromosomes by the NHLBI Exome Seq uencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs377303143). 13C>T in the 3' UTR of LAMP2 (rs377303143, allele frequency = 1/6728) ** -
