| Mendeliome v1.2351 | CFAP47 | Chirag Patel changed review comment from: 3 individuals with bilateral kidney cysts with mild enlargement of kidneys (mean age at Dx ~70yrs). They were all undergoing treatment for hypertension, had mean eGFR of ~31, None of them had any liver cysts or any family history of cystic kidney disease. WGS after negative clinical diagnostic testing, identified 3 missense variants in CFAP47 gene [p.(Arg870Gln), p.(Phe516Cys), and p.(Gly6Asp)]. The variants were rare in gnomAD but had equivocal in silico prediction scores, and would be reported as VUS using ACMG criteria. Segregation was not possible as their mothers were deceased. CFAP47 encodes cilia and flagella associated protein 47 a protein that plays a role in the formation and function of cilia and flagella. It is is expressed in primary cilia of human kidney tubules. Knockout (KO) mice exhibited larger kidneys with vacuolation of tubular cells and tubular dilation, providing evidence that CFAP47 is a causative gene involved in cyst formation.; to: 3 Japanese individuals with bilateral kidney cysts with mild enlargement of kidneys (mean age at Dx ~70yrs).

| Mendeliome v1.2129 | APOA4 |
Zornitza Stark gene: APOA4 was added gene: APOA4 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: APOA4 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: APOA4 were set to 38096951 Phenotypes for gene: APOA4 were set to Hereditary amyloidosis, MONDO:0018634, APOA4-related Review for gene: APOA4 was set to GREEN Added comment: 5 families with autosomal dominant medullary amyloidosis. WGS/WES identified 2 different variants in the APOA4 gene (p.D33N in 3 families and p.L66V in 2 families). The variants were absent in gnomAD, located at the structurally flexible N-terminal domain of APOA4, and segregated with disease. There were 48 genotype +ve individuals with 44/48 having an eGFR <60. All clinically affected individuals presented with a bland urinary sediment, CKD, and no clinical evidence of systemic amyloidosis. Mean age of dialysis/transplantation was 58+/-11yrs. Routine kidney biopsies limited to the kidney cortex showed tubulointerstitial fibrosis and secondary glomerulosclerosis and no amyloid deposition. Four affected individuals were shown to have isolated medullary deposition of amyloid, with mass spectrometry showing the mutated Apoa4 as the primary constituent in 3 available cases. Plasma total ApoA4 levels were increased for patients (n=15) with ApoA4 mutations versus controls (n=49). They hypothesize that the amino acid substitutions alter the tertiary or quaternary structure of the mutated ApoA4, leading to increased plasma and primary urine concentrations and isolated medullary amyloid deposition.

| Mendeliome v1.1381 | KDR |
Zornitza Stark edited their review of gene: KDR: Added comment: PMID 34113005: Exome sequencing in a family with two siblings affected by ToF revealed biallelic missense variants in KDR. Studies in knock-in mice and in HEK 293T cells identified embryonic lethality for one variant when occurring in the homozygous state, and a significantly reduced VEGFR2 phosphorylation for both variants. Rare variant burden analysis conducted in a set of 1,569 patients of European descent with ToF identified a 46-fold enrichment of protein-truncating variants (PTVs) in TOF cases compared to controls (P = 7 × 10-11). At this stage MOI unclear and insufficient evidence for either MOI.; Changed publications: 31980491, 29650961, 18931684, 34113005; Changed phenotypes: Pulmonary hypertension, Haemangioma, capillary infantile, somatic 602089, Tetralogy of Fallot, MONDO:0008542; Changed mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal |
