Genes affected

LAMTOR5 (HGNC:17955): (late endosomal/lysosomal adaptor, MAPK and MTOR activator 5) This gene encodes a protein that specifically complexes with the C-terminus of hepatitis B virus X protein (HBx). The function of this protein is to negatively regulate HBx activity and thus to alter the replication life cycle of the virus. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.340G>A (p.G114S) alteration is located in exon 2 (coding exon 2) of the LAMTOR5 gene. This alteration results from a G to A substitution at nucleotide position 340, causing the glycine (G) at amino acid position 114 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
