Genes affected

LAMTOR2 (HGNC:29796): (late endosomal/lysosomal adaptor, MAPK and MTOR activator 2) The product of this gene is highly conserved with a mouse protein associated with the cytoplasmic face of late endosomes and lysosomes. The mouse protein interacts with MAPK scaffold protein 1, a component of the mitogen-activated protein kinase pathway. In humans, a mutation in this gene has been associated with a primary immunodeficiency syndrome, and suggests a role for this protein in endosomal biogenesis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2009]

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.
