In summary, our results indicate that a familial MDS-associated HLTFE259K germline mutation induces accumulation of DNA double-strand breaks, possibly through impaired PCNA polyubiquitination.
More recently, studies have also potentially linked Cytl1 with a variety of conditions including cardiac fibrosis, smoking, alcohol dependence risk, and tumours such as benign prostatic hypertrophy, lung squamous cell carcinoma, neuroblastoma and familial colorectal cancer.
This study broadens the genotypic spectrum of NPR2 mutations in individuals with AMDM and also describes the intra- and inter-familial phenotypic variability due to NPR2 variants.
Fifty-three women pregnant with a fetus affected by cardiac tumor(s) were examined by standardized fetal echocardiography (FE), and fetuses, mothers and fathers, including other relevant family members if necessary, underwent familialTSC genetic testing.
Specifically, rare loss-of-function variants in the N-terminal pyrin domain indicate that this part of NLRP1 is autoinhibitory and normally acts to prevent a familial autoinflammatory skin disease associated with cancer.
However, only whole genome sequencing (WGS) in combination with the Manta algorithm for analyses of structural variants revealed a heterozygous 24 kB inversion including exon 1 of CCM2 in a 12-year-old boy with familial CCMs.
More recently, mutations in LACC1 (laccase domain-containing protein 1) have been identified as the cause of a monogenic form of systemic juvenile idiopathic arthritis, which does not itself manifest granulomatous inflammation, but the same LACC1 mutations have also been shown to cause an early-onset, familial form of a well-known granulomatous condition, Crohn's disease (CD).
Our current knowledge about the cellular mechanisms underlying serpin-related disorders, the serpinopathies, is predominantly based on studies in cell culture models of disease, particularly for alpha-1 antitrypsin (AAT, SERPINA1) deficiency causing emphysema and the familial encephalopathy with neuroserpin (NS, SERPINI1) inclusion bodies (FENIB).
Here, we investigated the effect of MIR137 genotype on white matter fractional anisotropy (FA), cortical thickness (CT), and surface area (SA) in a sample comprising healthy control subjects, and individuals with familial risk for psychosis (first-degree relatives of patients with schizophrenia or bipolar disorder; N=426).
However, more recently, inherited SWI/SNF-deficiency has been linked to several benign syndromic tumors including a subset of familial schwannomatosis (linked to SMARCB1) and multiple meningiomas (linked to SMARCE1) as well as others.
By wholeexome sequencing, a homozygous frameshift mutation in DPH1 (c.1227delG, p.[Ala411Argfs*91]) was identified, which is likely responsible for the familial condition.
Mechanistically, the entities include generalized pustular psoriasis (GPP) without psoriasis vulgaris, impetigo herpetiformis and acrodermatitis continua, which are IL-36Ra-related pustuloses caused by loss-of-function mutations in IL36RN; GPP with psoriasis vulgaris and palmoplantar pustular psoriasis which are CARD14-mediated pustular psoriasiform dermatoses with gain-of-function variants of CARD14; PRP type V which is caused by gain-of-function mutations in CARD14; and, familial KLC in which mutations in NLRP1, an inflammasome sensor protein predominantly expressed in skin, have been identified.
The association is specific to participants who have already developed knee osteoarthritis, suggesting that the COL11A2 gene, which has previously been associated with familial osteoarthritis, may play a role in pain sensitization after the development of osteoarthritis.
