Mendeliome v1.4796 SLC20A2 Zornitza Stark Publications for gene: SLC20A2 were set to 22327515; 23334463; 24209445; 23437308; 32705272; 27943094
Mendeliome v1.4795 SLC20A2 Zornitza Stark Mode of inheritance for gene: SLC20A2 was changed from MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted to BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal
Mendeliome v1.4794 SLC20A2 Zornitza Stark edited their review of gene: SLC20A2: Added comment: PMID 41458256: Reports a single individual a homozygous nonsense SLC20A2 variant presenting with infantile primary familial brain calcification, cerebral arterial vasculopathy and ischaemic stroke. Individual exhibited seizures, hypotonia, poor feeding, and extensive ischaemic changes.

PMID 35881308: reports two siblings from a consanguineous Turkish family with a homozygous splice‑site loss‑of‑function variant NM_006749.5:c.1794+1G>A. The affected children presented with severe paediatric‑onset features resembling congenital CMV infection: growth retardation, bilateral cataracts, microcephaly, seizures, cerebral atrophy, corpus callosum hypoplasia and brain microcalcifications.

PMID 34267336 reports a consanguineous family including a 55‑year‑old woman homozygous for the missense variant c.211C>T (p.Arg71Cys) who had extensive basal ganglia calcifications, psychiatric manifestations and progressive Parkinsonism.; Changed publications: 22327515, 23334463, 41458256, 35881308, 34267336; Changed mode of inheritance: BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal
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).
