Ivone Leong gene: MTX2 was added gene: MTX2 was added to Skeletal dysplasia. Sources: Literature for-review tags were added to gene: MTX2. Mode of inheritance for gene: MTX2 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: MTX2 were set to 32917887 Phenotypes for gene: MTX2 were set to Skeletal dysplasia; Mandibuloacral dysplasia; lipodystrophy; arterial calcification Review for gene: MTX2 was set to GREEN Added comment: The Genomics England Clinical Team suggested that this gene should be added to this panel as there are enough skeletal features for it to be here. Therefore, this gene has been given an Amber rating and will be promoted to Green at the next review. Review from Zornitza Stark on the Lipodystrophy - childhood onset: "Seven individuals from 5 unrelated families reported with severe progeroid form of MAD with growth retardation, small viscerocranium with mandibular underdevelopment, distal acro-osteolyses, lipodystrophy, altered skin pigmentation, renal focal glomerulosclerosis, and extremely severe hypertension in most cases, eventually associated with disseminated arterial calcification. Loss of MTX2 in patients' primary fibroblasts led to loss of Metaxin-1 (MTX1) and mitochondrial dysfunction, including network fragmentation and oxidative phosphorylation impairment. Furthermore, patients' fibroblasts were resistant to induced apoptosis, leading to increased cell senescence and mitophagy and reduced proliferation.
