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.494C>T (p.T165M) alteration is located in exon 4 (coding exon 4) of the LAMTOR5 gene. This alteration results from a C to T substitution at nucleotide position 494, causing the threonine (T) at amino acid position 165 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
