Genes affected

MTBP (HGNC:7417): (MDM2 binding protein) This gene encodes a protein that interacts with the oncoprotein mouse double minute 2. The encoded protein regulates progression through the cell cycle and may be involved in tumor formation. [provided by RefSeq, Aug 2012]

Ambry Genetics

Mar 26, 2024

The c.852A>G (p.I284M) alteration is located in exon 8 (coding exon 8) of the MTBP gene. This alteration results from a A to G substitution at nucleotide position 852, causing the isoleucine (I) at amino acid position 284 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
