Extreme early-onset hypertension v1.21 CYP11B2 Achchuthan Shanmugasundram changed review comment from: Autosomal recessive variants in CYP11B2 causes Hypoaldosteronism, congenital, due to CMO I deficiency (MIM #203400) and due to CMO II deficiency (MIM #610600). Patients with these disorders present with salt loss and failure to thrive in early childhood and they do not present with hypertension.

Glucocorticoid-remediable aldosteronism (GRA, MIM #103900) is an autosomal-dominant disorder caused by chimeric duplication of CYP11B1 and CYP11B2 genes. These patients present with early-onset hypertension. Hence, the MOI in this should be 'MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted' rather than 'BIALLELIC, autosomal or pseudoautosomal' as in 'Congenital adrenal hypoplasia' panel.; to: Autosomal recessive variants in CYP11B2 causes Hypoaldosteronism, congenital, due to CMO I deficiency (MIM #203400) and due to CMO II deficiency (MIM #610600).

Extreme early-onset hypertension v1.19 CYP11B1 Arina Puzriakova Added comment: Comment on mode of inheritance: Familial hyperaldosteronism characterised by hypertension is caused by chimeric fusion of CYP11B1/CYP11B2 (monoallelic to pick this up), while biallelic variants in the CYP11B1 is associated with congenital adrenal hyperplasia which also presents with early-onset moderate to severe hypertension among other features. Therefore updating MOI to 'Both mono- and biallelic'.

Extreme early-onset hypertension v1.14 TTC21B John Sayer edited their review of gene: TTC21B: Added comment: Careful literature review supports the notion that biallelic, often hypomorph, missense variants in TTC21B are commonly associated with early-onset hypertension and histological features of both FSGS and NPHP. Increased clinical recognition of this mixed glomerular and tubulointerstitial disease with often mild or absent features of a typical ciliopathy as well as inclusion of TTC21B on gene panels for early-onset arterial hypertension might shorten the diagnostic odyssey for patients affected by this rare tubuloglomerular kidney disease.; Changed publications to: 24876116, 26940125, 34957165, 34805047, PMID: 35289079

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. Sources: Literature
