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]

Jun 13, 2024

The c.489A>T (p.R163S) alteration is located in exon 6 (coding exon 6) of the MTBP gene. This alteration results from a A to T substitution at nucleotide position 489, causing the arginine (R) at amino acid position 163 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
