Mendeliome v1.989 NAA60 Chirag Patel gene: NAA60 was added
gene: NAA60 was added to Mendeliome. Sources: Other
Mode of inheritance for gene: NAA60 was set to BIALLELIC, autosomal or pseudoautosomal
Phenotypes for gene: NAA60 were set to Basal ganglia calcification
Review for gene: NAA60 was set to GREEN
gene: NAA60 was marked as current diagnostic
Added comment: ESHG 2023:
10 individuals from 7 families with biallelic variants in NAA60 (missense and framshift).
All with primary brain calcification - 4/10 childhood onset (DD, ID), 6/10 adult onset (cerebellar and pyramidal dysfunction, dystonia, parkinsonism, cognitive impairment, psychiatric manifestations).

NAA60 catalyses N-terminal acetylation of transmembrane proteins and localises to Golgi apparatus. In vitro assay of variants showed reduced capacity of Nt acetylation. Fibroblast studies showed significantly reduced levels of phosphate importer (SLC20A2). Loss of function variants in SLC20A2 (~50% of PFBC cases) lead to increased extracellular phosphate (which is thought to lead to calcium deposits in brain).
