WebIn the sural nerve, dystrophic axons had focally uncompacted myelin lamellae present. Genetic investigation revealed multiple mtDNA deletion and compound heterozygous mutations of the TWNK gene (c.1196 A > G, c.1358 G > A). This study demonstrates that TWNK associated Perrault syndrome has a much broader phenotype as originally published. WebJul 29, 2024 · Mitochondrial gene mutations can be heterogeneous or homogeneous and cause a disease phenotype when mutations exceed threshold levels. Often, there is a correlation between the rate of mutation and the expression of the disease phenotype, and sometimes different mutations occur in different tissues [ 3 ].
