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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 02, 2024The c.131C>G (p.A44G) alteration is located in exon 2 (coding exon 2) of the MTBP gene. This alteration results from a C to G substitution at nucleotide position 131, causing the alanine (A) at amino acid position 44 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
