Green List (high evidence)

This gene is linked to Hereditary hyperekplexia and Sulfite oxidase deficiency due to molybdenum cofactor deficiency type C in Orphanet. PMID: 26613940 - homozygous patient with epileptic encephalopathy reported. PMID: 24561070 microdeletions paternally inherited reported in probands with epileptic encephalopathy from 2 families. Perhaps further evidence provided in PMID 25866352 for role of the gene in neurodevelopmental disorders with seizures. PMID 23393157 - 6 additional cases of microdeletions affecting different exons in the gene, in patients with Autism spectrum disorder, seizures or schizophrenia. PMID 23275889 de novo CNV identified in a patient with Autism spectrum disorder. For Molybdenum cofactor deficiency, PMID 22040219 reports a homozygous missense variant in a child with global hypotonia and generalised seizures. PMID 11095995 reports a homozygous deletion in a patient with Molybdenum Cofactor Deficiency. Tagged with the 'treatable' tag as molybdate supplementation according to PMID: 11095995.
