Abstract

The syndrome of mitochondrial encephalopathy, lactic acidosis, and stroke-like episode (MELAS) is characterized clinically by recurrent focal neurological deficits, epilepsy, and short stature. The phenotypic spectrum is extremely diverse, with multisystemic organ involvement leading to isolated diabetes, deafness, renal tubulopathy, hypertrophic cardiomyopathy, and retinitis pigmentosa. In 80% of cases, the syndrome is associated with an AG transmission mutation (A3243G) in the tRNALeu gene of the mitochondrial DNA (mtDNA). We describe a woman with a unique combination of the MELAS A3243G mutation and multiple mtDNA deletions with normal POLG sequence. The patient presented with diabetes mellitus, sensorineural deafness, short stature, and mental disorientation. All her three children died in early adolescence.
