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]

The c.229G>A (p.V77M) alteration is located in exon 4 (coding exon 4) of the LAMTOR4 gene. This alteration results from a G to A substitution at nucleotide position 229, causing the valine (V) at amino acid position 77 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
