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]

The c.610G>A (p.A204T) alteration is located in exon 6 (coding exon 6) of the MTBP gene. This alteration results from a G to A substitution at nucleotide position 610, causing the alanine (A) at amino acid position 204 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
