| Disease ID | Source | Name | Description |
| 618913 | OMIM | Fanconi renotubular syndrome 5 (FRTS5) | A form of Fanconi renotubular syndrome, a disease due to a generalized dysfunction of the proximal kidney tubule resulting in decreased solute and water reabsorption. Patients have polydipsia and polyuria with phosphaturia, glycosuria and aminoaciduria. They may develop hypophosphatemic rickets or osteomalacia, acidosis and a tendency toward dehydration. Some eventually develop renal insufficiency. FRTS5 is an autosomal recessive mitochondrial disorder characterized by proximal renotubular dysfunction from birth, followed by progressive kidney disease and pulmonary fibrosis. The disease is caused by variants affecting the gene represented in this entry. A homozygous disease-causing variant located in intron 2 leads to aberrant splicing and altered isoform synthesis. Kidney and lung tissues from affected individuals show specific loss of mitochondrial isoform 1. Patient cells show defects in mitochondrial complex I assembly and altered mitochondrial respiration. |
| 618239 | OMIM | Mitochondrial complex I deficiency, nuclear type 17 (MC1DN17) | A form of mitochondrial complex I deficiency, the most common biochemical signature of mitochondrial disorders, a group of highly heterogeneous conditions characterized by defective oxidative phosphorylation, which collectively affects 1 in 5-10000 live births. Clinical disorders have variable severity, ranging from lethal neonatal disease to adult-onset neurodegenerative disorders. Phenotypes include macrocephaly with progressive leukodystrophy, non-specific encephalopathy, cardiomyopathy, myopathy, liver disease, Leigh syndrome, Leber hereditary optic neuropathy, and some forms of Parkinson disease. MC1DN17 transmission pattern is consistent with autosomal recessive inheritance. The disease is caused by variants affecting the gene represented in this entry. |
