Question: Which pathological conditions are caused by mutations in the CYLD gene?

Context:
We detected a frameshift mutation in the CYLD gene, designated 2253delG, underlying the disorder and were able to show that a single mutation can result in distinct clinical and histologic expression in familial cylindromatosis.
Previously, a candidate MTF locus has been mapped to 9p21 while disease gene for familial cylindromatosis, the CYLD gene located on 16q21-13 has been identified
Here, we show that mutations in the CYLD gene are also the genetic basis for three different Chinese families with MFT
familial trichoepithelioma (MFT) and familial cylindromatosis are two clinically distinct cancer syndromes. MFT patients developed mostly trichoepithelioma in the face while cylindromatosis patients developed cylindromas predominantly (approximately 90%) on the head and neck
phenotype of familial cylindromatosis associated with an R758X nonsense mutation in the CYLD tumour suppressor gene
We describe a family with cylindromatosis, in which affected individuals have an inherited R758X nonsense mutation of CYLD
YLD mutations underlie Brooke-Spiegler, familial cylindromatosis, and multiple familial trichoepithelioma syndromes
We describe a single family with affected members exhibiting either the FC or the MFT phenotypes associated with a mutation in the CYLD gene. 
ndividuals with germline mutations in the tumour-suppressor gene CYLD are at high risk of developing disfiguring cutaneous appendageal tumours, the defining tumour being the highly organised cylindroma
YLD is a tumor-suppressor gene mutated in the skin appendage tumors cylindromas, trichoepitheliomas, and spiradenomas. 
In addition, we have characterized Maspin downregulation in cylindromas, trichoepitheliomas, and spiradenomas carrying functional inactivating mutations of CYLD, also providing an evidence of the correlation between impaired CYLD function and Maspin decreased expression in vivo in human tumors
Germ‑line mutation in cylindromatosis (CYLD), a tumor suppressor gene, causes familial cylindromatosis and Brook‑Spiegler syndrome
atients carrying heterozygous germline truncating mutations in the CYLD gene develop multiple primary hair follicle-related tumours. A highly patterned tumour, termed cylindroma, and a highly disorganized tumour, termed spiradenoma, may both develop in the same patient.
ultiple trichoepitheliomas associated with a novel heterozygous mutation in the CYLD gene as an adjunct to the histopathological diagnosis
ultiple trichoepitheliomas (TEs), especially in the familial setting, have been associated with germline heterozygous mutations in the CYLD gene
We describe a 35-year-old woman with multiple facial TEs, in whom the molecular genetic analysis revealed a novel heterozygous c.1843delT mutation in the CYLD gene
This frameshift mutation was also present in a heterozygous state in the TE tumor cells. The demonstration of a novel CYLD mutation was used as an adjunct to the histopathological diagnosis in this case
novel germline mutation in the CYLD gene in a Slovak patient with Brooke-Spiegler syndrome
This new germline mutation in the CYLD gene of a Slovak patient with Brooke-Spiegler syndrome extends the catalogue of known CYLD germline mutations in this condition
Molecular biologic study of the CYLD gene performed from the peripheral blood identified a novel splice site c.2041+1 G>T mutation
Patients with Brooke-Spiegler syndrome have various mutations in the CYLD gene, a tumor-suppressor gene located on chromosome 16q
Mutation and loss of heterozygosity of the CYLD gene causes development of cylindromatosis, a benign tumour originating from the skin
Our study shows that CYLD expression is dramatically downregulated in basal cell carcinoma (BCC), the most common cancer in humans
Although some early studies suggested a role for the PTCH gene on chromosome 9q22.3 in the etiopathogenesis of MFT, recent studies of occasional patients with the MFT clinical phenotype identified mutations in the CYLD gene on chromosome 16q12-q13, a gene responsible for BSS
Since loss of CYLD expression can be observed in different types of human cancer, it is now well established that CYLD acts as a tumor suppressor gene
mutations in CYLD can be identified in patients affected with Brooke-Spiegler syndrome, (Familial) Cylindromatosis or multiple familial trichoepithelioma
we demonstrate that the expression in tumorigenic epidermal cells of a catalytically inactive form of CYLD (CYLD(C/S)) that mimics the identified mutations of cyld in human tumors and competes with the endogenous CYLD results in enhanced cell proliferation and inhibition of apoptosi
In contrast with previous studies showing the development of benign tumors by mutations in the CYLD gene, here we provide evidence that the occurrence of mutations in the CYLD gene in tumorigenic epidermal cells (carrying previous mutations) increases the aggressiveness of carcinomas, mainly through enhancement of the expression of angiogenic factors, having therefore a key role in epidermal cancer malignancy
By interphase cytogenetics, a (sub)clonal biallelic CYLD deletion was observed by interphase cytogenetics in 1 of 29 primary cHL, whereas signal patterns indicating decreased CYLD copy numbers were observed in a total of 10 of 29 primary cases
mutation in the CYLD gene within a family with Brooke-Spiegler syndrome
rooke-Spiegler syndrome is a rare, autosomal dominant disease characterized by multiple skin appendage tumors caused by various mutations in the CYLD gene on chromosome 16q12-q13
authors report a case of Brooke-Spiegler syndrome (BSS) with a novel germline CYLD mutation and various somatic mutations identified in the lesional tissues
he available histopathological material included 24 trichoepitheliomas, 2 large nodular basal cell carcinomas (BCCs), 2 spiradenomas, 1 spiradenocylindroma and 1 trichoblastoma composed of large and small nodules with prominent clear cell differentiation
To comprehensively ascertain the extent and severity of clinical features in affected individuals from 2 large families with proven heterozygous mutations in the CYLD locus and to correlate these findings with the 3 appendageal tumor predisposition syndromes (familial cylindromatosis, Brooke-Spiegler syndrome, and multiple familial trichoepitheliomas) known to be associated with such germline mutations
In this report, we identified a novel mutation of CYLD gene in a Chinese family with MFT
case of Brooke-Spiegler syndrome with a novel germline deep intronic mutation in the CYLD gene leading to intronic exonization, diverse somatic mutations, and unusual histology
present a case of Brooke-Spiegler syndrome with a germline deep intronic mutation in the CYLD gene leading to intronic exonization
A deep intronic mutation resulting in exonization and a somatic sequence mutations causing exon skipping are hitherto unreported genetic mechanisms involving the CYLD gene in patients with Brooke-Spiegler syndrome
novel splicing mutation of the CYLD gene in a Taiwanese family with multiple familial trichoepithelioma
Mutations in the CYLD gene, which is also the gene responsible for familial cylindromatosis, have been reported recently
We report a novel splicing mutation (IVS12 + 1 G-->A) in the CYLD gene in a Taiwanese pedigree with MFT, and discuss new developments in treatment options
new CYLD mutations in skin appendage tumors and evidence that aspartic acid 681 in CYLD is essential for deubiquitinase activity
rooke-Spiegler syndrome, familial cylindromatosis, and familial trichoepithelioma are autosomal-dominant genetic predispositions for benign tumors of skin appendages caused by mutations in the CYLD gene localized on chromosome 16q12-q13
The disease gene was mapped to 16q12-13, and mutations in the CYLD gene were identified in families with BSS
By sequence analysis, we identified a recurrent mutation 2272C>T (R758X) of the CYLD gene in the affected individuals of this family, which was previously identified in other ethnic families with familial cylindromatosis

Answer: Since loss of CYLD expression can be observed in different types of human cancer, it is now well established that CYLD acts as a tumor suppressor gene. Pathogenic mutations in CYLD can be identified in patients affected with Brooke-Spiegler syndrome, (Familial) Cylindromatosis or multiple familial trichoepithelioma. CYLD expression has also been reported to be  dramatically downregulated in basal cell carcinoma (BCC), the most common cancer in humans.
Exact answer: Brooke-Spiegler syndrome, BSS, Cylindromatosis, Multiple Familial Trichoepithelioma, MFT
