Prepair 1000+ v1.1816 MTPAP Zornitza Stark Tag for review tag was added to gene: MTPAP.
Prepair 1000+ v1.1811 MTPAP Andrew Coventry gene: MTPAP was added
gene: MTPAP was added to Prepair 1000+. Sources: Literature
Mode of inheritance for gene: MTPAP was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: MTPAP were set to 20970105; 33340416; 32376682; 15769737; 31779033; 35235001; 27391121
Phenotypes for gene: MTPAP were set to Mitochondrial disease MONDO:0044970
Review for gene: MTPAP was set to GREEN
Added comment: Definitive disease-gene classification by ClinGen - "Identified in five individuals from four publications (PMIDs: 20970105, 31779033, 35235001, 27391121). Supported by a biochemical function (mitochondrial translation) shared with other genes associated with primary mitochondrial disease, early embryonic lethality and failure of developmental progression in a knockout mouse model, and disrupted expression of mitochondrial proteins and mitochondrial dysfunction following gene knockdown in HeLa cells (PMIDs: 33340416, 32376682, 15769737)."

Note that 6 individuals with spastic ataxia all had same founder variant and were traced as distantly related (Amish community - c.1432A>G (p.Asn478Asp).
Further additional families reported with a much more severe phenotype of lethal encephalopathy.

Phenotypes previous reported to be associated with MTPAP are likely to represent a continuum of severity associated with a mitochondrial disorder.
Clingen "While various names have been given to the constellation of features seen in those with MTPAP-related disease, including autosomal recessive spastic ataxia 4 (SPAX4) (MIM 613672) in additional to other mitochondrial disorders, pathogenic variants in this gene cause a primary mitochondrial disease.... lumped into one disease entity..."
