Cardiomyopathy and deafness due to tRNA lysine gene mutation
Other Names for this Disease
- Cardiomyopathy and deafness due to MTTK gene mutation
MTTK gene causes a condition characterized by weakened heart muscle (cardiomyopathy) and hearing loss. Affected individuals may also have myopathy and ataxia. This mutation replaces the DNA building block (nucleotide) guanine with the nucleotide adenine at position 8363 (written as G8363A) within the gene. It is unclear how this alteration in the MTTK gene results in cardiomyopathy, hearing loss, and other symptoms.A specific change in the
