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 GeneticsJun 14, 2023The c.279T>G (p.C93W) alteration is located in exon 4 (coding exon 4) of the MTBP gene. This alteration results from a T to G substitution at nucleotide position 279, causing the cysteine (C) at amino acid position 93 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
