Genes affected

LAMTOR3 (HGNC:15606): (late endosomal/lysosomal adaptor, MAPK and MTOR activator 3) This gene encodes a scaffold protein that functions in the extracellular signal-regulated kinase (ERK) cascade. The protein is localized to late endosomes by the mitogen-activated protein-binding protein-interacting protein, and binds specifically to MAP kinase kinase MAP2K1/MEK1, MAP kinase MAPK3/ERK1, and MAP kinase MAPK1/ERK2. Studies of the orthologous gene in mouse indicate that it regulates late endosomal traffic and cell proliferation. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. A pseudogene of this gene is located on the long arm of chromosome 13.

The c.313A>G (p.S105G) alteration is located in exon 7 (coding exon 6) of the LAMTOR3 gene. This alteration results from a A to G substitution at nucleotide position 313, causing the serine (S) at amino acid position 105 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
