Genes affected

LAMTOR4 (HGNC:33772): (late endosomal/lysosomal adaptor, MAPK and MTOR activator 4) Contributes to guanyl-nucleotide exchange factor activity and molecular adaptor activity. Involved in several processes, including cellular response to amino acid stimulus; positive regulation of TOR signaling; and protein localization to lysosome. Located in lysosome. Part of Ragulator complex. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Sep 30, 2022

The c.160C>T (p.R54W) alteration is located in exon 3 (coding exon 3) of the LAMTOR4 gene. This alteration results from a C to T substitution at nucleotide position 160, causing the arginine (R) at amino acid position 54 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
