Zornitza Stark edited their review of gene: APOO: Added comment: PMID: 37649161 1 family, 2 individuals (male & female) with same NMD variant c.532G>T (p.E178*), maternally inherited (mother unaffected). Both died before 18 months of age with partial agenesis of the corpus callosum, bilateral congenital cataract, hypothyroidism, and severe immune deficiencies. Other phenotypes included partial syndactyly of the 2nd and 3rd toes, wrinkled palm, and sole skin. Functional studies included site directed mutagenesis. This mutation resulted in a highly unstable and degradation prone MIC26 protein, yet the remaining minute amounts of mutant MIC26 correctly localized to mitochondria and interacted physically with other MICOS subunits. MIC26 KO cells expressing MIC26 harboring the respective APOO/MIC26 mutation showed mitochondria with perturbed cristae architecture and fragmented morphology resembling MIC26 KO cells.; Changed publications: 37649161; Changed phenotypes: Mitochondrial disease, MONDO:0044970, APOO-related, Developmental delay, Lactic acidosis, Muscle weakness, Hypotonia, Repetitive infections, Cognitive impairment, Autistic behaviour |

Arina Puzriakova gene: APOO was added gene: APOO was added to Mendeliome. Sources: Literature Mode of inheritance for gene: APOO was set to X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males) Publications for gene: APOO were set to 32439808 Phenotypes for gene: APOO were set to Developmental delay; Lactic acidosis; Muscle weakness; Hypotonia; Repetitive infections; Cognitive impairment; Autistic behaviour Review for gene: APOO was set to RED Added comment: - PMID: 32439808 (2021) - Three generation family with c.350T>C variant in APOO, encoding a component of the MICOS complex which plays a role in maintaining inner mitochondrial membrane architecture. Phenotypes include fatigue and muscle weakness (6/8), learning difficulties and cognitive impairment (4/8), and increased blood lactate (2/8). Four individuals were asymptomatic carriers, including one male (authors indicate variability in female carriers was due to skewed X-inactivation, although skewing studies were inconclusive in some cases). Variability in clinical presentation suggests reduced penetrance or possible contribution of additional factors. Functional studies showed altered MICOS assembly and abnormalities in mitochondria ultrastructure in patient-derived fibroblasts. Knockdown studies in Drosophila and yeast demonstrated mitochondrial structural and functional deficiencies. Sources: Literature |
