Compound heterozygous CORO1A mutations in siblings with a mucocutaneous-immunodeficiency syndrome of epidermodysplasia verruciformis-HPV, molluscum contagiosum and granulomatous tuberculoid leprosy. J Clin Immunol 2014; 34:871-90.

Abstract
PURPOSE Coronin-1A deficiency is a recently recognized autosomal recessive primary immunodeficiency caused by mutations in CORO1A (OMIM 605000) that results in T-cell lymphopenia and is classified as T(-)B(+)NK(+)severe combined immunodeficiency (SCID). Only two other CORO1A-kindred are known to date, thus the defining characteristics are not well delineated. We identified a unique CORO1A-kindred. METHODS We captured a 10-year analysis of the immune-clinical phenotypes in two affected siblings from disease debut of age 7 years. Target-specific genetic studies were pursued but unrevealing. Telomere lengths were also assessed. Whole exome sequencing (WES) uncovered the molecular diagnosis and Western blot validated findings. RESULTS We found the compound heterozygous CORO1A variants: c.248_249delCT (p.P83RfsX10) and a novel mutation c.1077delC (p.Q360RfsX44) (NM_007074.3) in two affected non-consanguineous siblings that manifested as absent CD4CD45RA(+) (naïve) T and memory B cells, low NK cells and abnormally increased double-negative (DN) ϒδ T-cells. Distinguishing characteristics were late clinical debut with an unusual mucocutaneous syndrome of epidermodysplasia verruciformis-human papilloma virus (EV-HPV), molluscum contagiosum and oral-cutaneous herpetic ulcers; the older female sibling also had a disfiguring granulomatous tuberculoid leprosy. Both had bilateral bronchiectasis and the female died of EBV+ lymphomas at age 16 years. The younger surviving male, without malignancy, had reproducibly very short telomere lengths, not before appreciated in CORO1A mutations. CONCLUSION We reveal the third CORO1A-mutated kindred, with the immune phenotype of abnormal naïve CD4 and DN T-cells and newfound characteristics of a late/hypomorphic-like SCID of an EV-HPV mucocutaneous syndrome with also B and NK defects and shortened telomeres. Our findings contribute to the elucidation of the CORO1A-SCID-CID spectrum.

Abstract
Infections with human papillomaviruses (HPV) are a common occurrence in both men and women. In contrast HPV-associated neoplasias are relatively rare and occur only in certain areas of the body. The virus has obviously developed efficient mechanisms for its persistence without inducing too much damage to the host. The formation of neoplasia seems to be more an exception. Epigenetic mechanisms play an important role in the regulation of viral gene expression. Investigations have indicated that exactly the transition from the permissive infection stage to a transformation stage, where neoplastic alterations can occur due to expression of the viral oncogenes, is associated with certain methylation patterns of the viral genome which promote the expression of the oncogenes E6 and E7. The transforming stage is seen as the actual carcinogenic event and can be immunohistochemically detected by the biomarker p16(INK4a).

Abstract
Lewandowsky and Lutz dysplasia, also known as epidermodysplasia verruciformis (EV), is an inherited disorder in which there is widespread and persistent infection with human papilloma virus, defect in cell-mediated immunity and propensity for malignant transformation. Differential clinical and histopathologic evolutions of lesions in two cases of familial EV are compared and discussed in detail. Cases were followed up for 7 years. Detailed history, clinical features and investigations, including skin biopsy from different sites at different times, were examined. Generalized pityriasis versicolor like hypopigmented lesions in both the cases, together with variable pigmented nodular actinic keratosis like lesions on sun-exposed areas, were present. Multiple skin biopsies done from various sites on different occasions revealed features typical of EV along with lesions, i.e., actinic keratosis, Bowen's disease, basal and squamous cell carcinoma, in the elder sibling. However, skin biopsy of the other sibling showed features of EV and seborrheic keratosis only till date. This study reveals that the disease progression is variable among two individuals of the same family. Malignant lesions were seen only on sun-exposed areas and may be associated with other skin lesions or infections such as angiokeratoma of Fordyce and tinea cruris, as seen in this report.

Abstract
An increasing number of studies report that genus beta human papillomaviruses (HPVs) are associated with skin cancer, with suggestions of specificity for squamous cell carcinoma (SCC) of the skin. We have conducted a systematic examination of HPV DNA in tumors from immunocompetent hosts, including SCC and basal cell carcinoma (BCC), using a highly sensitive methodology and population-based samples to test the hypothesis that a differential prevalence of beta-HPVs exists between SCC (n=101) and BCC (n=101) tumors. When testing for all known beta-HPV types, we found no significant difference in HPV prevalence between the two histologies. However, SCC lesions were significantly more likely to be infected with HPV genus beta-species 1 (includes types 5 and 8), than BCC samples (P=0.01); this difference was not observed for any other species. A histologic difference was also observed for those HPV types previously reported to be important in skin cancer (P=0.003). SCC samples showed a higher rate of infectivity (that is, were positive for multiple types) than BCC tumors (P=0.02). These data highlight the potential importance of various genus beta-HPV types, in particular genus beta-species 1 in SCC, and support the hypothesis of a behavioral difference of the virus within the two major histological skin cancers.

Abstract
Epidermodysplasia verruciformis (EV) is a rare disorder characterized by widespread human papillomavirus infection and malignant transformation. EV may be caused by mutations of the genes EVER1 or EVER2, which are located on the EV1 locus, 17q25. We describe a patient with EV and a novel homozygous gene mutation of EVER2 gene who was treated successfully with topical imiquimod.

Abstract
Epidermodysplasia verruciformis (EV) is a rare genetic skin disease with an autosomal recessive trait, and the patients have susceptibility to a specific group of human papillomavirus genotypes. Recently germline mutations in EVER1/2 genes have been detected in EV patients with different ethnic origins. In this study, we have applied PCR, single-stranded conformational polymorphism analysis, and sequencing as well as restriction fragment length polymorphism analysis for identifying potential mutation(s) of EVER genes in an EV patient and in the parents of Pakistani origin. A novel homozygous frameshift mutation (T base deletion at nucleotide position 968 of DNA) has been detected in the EVER1 gene of the patient. The parents carried this mutated allele in a heterozygous form. This is the third report on the presence of EVER1 mutations in an EV patient, and this result supports better understanding, diagnosis, and genetic counseling of EV patients.

Abstract
Epidermodysplasia verruciformis (EV) is a rare autosomal recessive genodermatosis associated with a high risk of skin carcinoma. EV results from an abnormal susceptibility to infection by specific human papillomavirus (HPV) genotypes (beta-papillomaviruses) which include the potentially oncogenic HPV5. EV-specific HPVs are considered as harmless for the general population. EV was recently found to be caused by invalidating mutations in two adjacent, related, novel genes, EVER1/TMC6 and EVER2/TMC8. EVER genes encode transmembrane proteins located in the endoplasmic reticulum, which are likely to function as modifiers of ion transporters or channels and to be involved in signal transduction. It was proposed that EV was a primary defect of innate immunity. Our hypothesis is that EVER proteins act as restriction factors for EV-specific HPVs in keratinocytes, and that EV represents a primary deficiency of intrinsic immunity against certain papillomaviruses.

Abstract
BACKGROUND The relation between human papillomavirus (HPV) and extragenital Bowen's disease (BD) is controversial. METHODS This study used in situ hybridisation to evaluate the rate of HPV in extragenital cutaneous BD and investigated possible relations with immune status and exposure of skin to light. RESULTS HPV DNA was detected in 58% of 69 samples from 50 patients. The percentage of HPV detection was not significantly higher in exposed (55%) than unexposed areas (65%), and no difference in HPV rate was found between immunosuppressed and immunocompetent patients. CONCLUSION Thus, this study confirms the high rate of HPV detection in extragenital cutaneous BD and suggests that there is no apparent relation concerning exposed areas and immune status.

Abstract
DNA damage, such as that elicited by UV-B, can induce either a cell cycle arrest or apoptosis that can be signalled by the p53 protein through the activation of a number of downstream cellular target genes. In contrast to oncogenic anogenital human papillomaviruses (HPVs), which mediate proteolytic degradation of p53, the E6 protein of cutaneous HPVs, such as HPV 77, do not promote p53 degradation. We have previously shown, however, that expression of HPV 77 E6 can effectively block UV-induced apoptosis in cells that have UV-activated p53. Here, we report that expression of the E6 protein from the cutaneous HPV 77 attenuates the UV-induced transactivation of p53-regulated proapoptotic genes Fas, PUMAbeta, Apaf-1, PIG3. This inhibition of p53-activation of proapoptotic genes by HPV77 E6 is exerted selectively, as the increased expression of p53 target genes involved in cell cycle arrest or regulatory functions regulation, such as p21 and Hdm2, is unaffected. Our data suggest that HPV 77 E6 may play an important role in specifically deregulating p53-dependent transactivation of proapoptotic genes upon UV-B irradiation.

Abstract
Papillomavirus was identified in pigmented epidermal plaques (PEP) from three dogs: a miniature schnauzer with hyperadrenocorticism and hypoglobulinemia, an American Staffordshire terrier with hypoglobulinemia, and a Pomeranian with unconfirmed hypothyroidism. Squamous cell carcinoma (SCC) arose within several plaques in the Pomeranian. Clinical improvement coincided in the first two cases with treatment of the concurrent disease and the administration of low-dose oral interferon-α. This is the first report of PEP in an American Staffordshire terrier and a Pomeranian. The potential for malignant transformation of PEP to SCC emphasizes the need for recognition and clinical management of PEP.

Abstract
The association between invasive cervical carcinoma and human papillomavirus (HPV) has now been established beyond doubt, but this is not necessarily a direct-and-effect association. To assess the causality of HPV, we analyzed HPV genomes in squamous cell carcinomas (SCCs) [corrected] of the uterine cervix by both blot hybridization and PCR. Genital HPV sequences were found in 231 (79%) of 294 SCCs by blot hybridization with more than five copies of entire HPV genomes identified in some cases including HPV 16 (92 cases), HPV 58 (32 cases), and HPV 52 (24 cases). By PCR-direct sequence analysis in 250 of 294 SCCs, genital HPV sequences were found in 240 samples (96%). The partial L1 sequences of HPV 16 were identified in 123 cases, and those of HPVs 18 and 31 were found in 24 and 20 cases, respectively. In addition, multiple HPV types were identified in 29 (12%) of 250 SCCs, and the HPV copy number, detected by PCR only, was less than 0.05. Marked discrepancies were therefore evident between the two analytical techniques. In this report, we discuss the causality of HPV for SCC with regard to the length of the viral genome, the amount of viral DNA, and multiple HPVs in single SCCs.

Abstract
Epidemiological and experimental studies have overwhelmingly confirmed human papillomaviruses as important causal agents in anogenital carcinogenesis. A role for human papillomaviruses has also been proposed in a diverse range of other malignancies, and particular interest has focused on non-melanoma skin cancer, the commonest malignancy in fair-skinned populations worldwide. Although the evidence for this is considerably less convincing than for anogenital cancer, important epidemiological and functional data have emerged over the past year that have furthered our understanding of the possible contribution of human papillomaviruses to skin cancer. Epidemiological human papillomavirus DNA detection studies have shown associations with non-melanoma skin cancer, but have also emphasized the ubiquity of epidermodysplasia verruciformis human papillomavirus types in normal skin, hair follicles and benign hyperproliferative disorders, as have seroepidemiological approaches. Functional investigations have demonstrated mechanistically relevant interactions between the virus and ultraviolet radiation, host cytokines and cellular proteins including p53 and the pro-apoptotic protein Bak. Taken together, these data have advanced our understanding of the contribution of human papillomaviruses to malignant transformation in cutaneous keratinocytes, but further research is required before a causal association between human papillomaviruses and skin cancer is reliably confirmed.

Abstract
Patients suffering from epidermodysplasia verruciformis are prone to nonmelanoma skin cancers, due to an inherited abnormal susceptibility to the oncogenic human papillomavirus type 5. Genotoxic sunlight ultraviolet B radiations are likely to be a cofactor. Lesions of two human-papillomavirus-type-5-infected epidermodysplasia verruciformis patients collected during an 8 y period were retrospectively studied for p53 mutations in exons 5 through 8 by a polymerase chain reaction single-strand conformation polymorphism technique and/or by DNA sequencing of amplified exons. Mutations were detected in 11 of 26 (42.3%) specimens, including five (62.5%) squamous cell carcinomas, three (33.3%) Bowen's carcinomas in situ, two (40%) actinic keratoses, and one (33%) benign lesion. The nine mutations characterized by sequencing were shown to be missense and to affect mutational hotspots in human cancers. Five were C-->T transitions at dicytidine sites considered as ultraviolet signature mutations. Two were transversions (C-->G and C-->A) at dicytidine sites and two were C-->T transitions at nondipyrimidine sites. A marked p53 immunoreactivity was disclosed in 72.7% of 11 invasive carcinomas, 55.6% of nine carcinomas in situ, 37.5% of eight actinic keratoses, and one of three benign lesions. This includes 81.8% of 11 specimens with a p53 mutation but also 50% of 14 specimens with no mutation detected. A dysfunction of the p53 gene is thus likely to play a part in epidermodysplasia verruciformis carcinogenesis, either due to ultraviolet-B-induced p53 mutations, as in nonmelanoma skin cancers in the general population, or involving other mutagens or mechanisms. The part played by human papillomavirus type 5 proteins expressed in epidermodysplasia verruciformis keratinocytes remains to be determined.
