Abstract
Hereditary gingival fibromatosis (HGF) is the most common genetic form of gingival fibromatosis which is featured as a localized or generalized overgrowth of gingivae. Currently two genes (SOS1 and REST), as well as four loci (2p22.1, 2p23.3–p22.3, 5q13–q22, and 11p15), have been identified as associated with HGF in a dominant inheritance pattern. Here, we report 13 individuals with autosomal-dominant HGF from a four-generation Chinese family. Whole-exome sequencing followed by further genetic co-segregation analysis was performed for the family members across three generations. A novel heterozygous missense mutation (c.2812G > A) in zinc finger protein 862 gene (ZNF862) was identified, and it is absent among the population as per the Genome Aggregation Database. The functional study supports a biological role of ZNF862 for increasing the profibrotic factors particularly COL1A1 synthesis and hence resulting in HGF. Here, for the first time we identify the physiological role of ZNF862 for the association with the HGF.

Abstract
Hypertrichosis is defined as an excessive growth in body hair beyond the normal variation compared with individuals of the same age, race and sex and affecting areas not predominantly androgen-dependent. The term hirsutism is usually referred to patients, mainly women, who show excessive hair growth with male pattern distribution.Hypertrichosis is classified according to age of onset (congenital or acquired), extent of distribution (generalized or circumscribed), site involved, and to whether the disorder is isolated or associated with other anomalies. Congenital hypertrichosis is rare and may be an isolated condition of the skin or a component feature of other disorders. Acquired hypertrichosis is more frequent and is secondary to a variety of causes including drug side effects, metabolic and endocrine disorders, cutaneous auto-inflammatory or infectious diseases, malnutrition and anorexia nervosa, and ovarian and adrenal neoplasms. In most cases, hypertrichosis is not an isolated symptom but is associated with other clinical signs including intellective delay, epilepsy or complex body malformations.A review of congenital generalized hypertrichosis is reported with particular attention given to the disorders where excessive diffuse body hair is a sign indicating the presence of complex malformation syndromes. The clinical course of a patient, previously described, with a 20-year follow-up is reported.

Abstract
Hereditary gingival fibromatosis (HGF) is a rare condition that can occur as an isolated disease, chromosomal abnormality, or as part of a number of syndromes. The gingival enlargement in HGF can be so severe that it can cover the crowns of teeth completely, causing severe functional derangement and facial disfigurement. Through review of literature revealed that HGF is usually an autosomal dominant condition, however the recessive forms are also reported. The hyperplastic gingiva is firm on palpation and has normal color with abundant stippling on the adjacent gingiva. The buccal and lingual gingiva may be involved in both the mandible and maxilla. The degrees of gingival enlargement show both intra- and interindividual variations. Here, an interesting case report of massive HGF has been presented.

Abstract
Zimmermann-Laband syndrome (ZLS) is a rare disorder characterized by gingival fibromatosis, hypertrichosis, intellectual disability, and absence and/or hypoplasia of the nails or terminal phalanges of the hands and feet. The syndromic features of ZLS are highly variable and can overlap with other entities featuring gingival fibrosis. This study describes a patient with ZLS with novel findings, including colpocephaly, hemivertebra, polydactyly, hyperpigmentation, and hemihyperplasia. Thus, the present report expands the phenotypic spectrum of this uncommon syndrome.

Abstract
Cherubism is an inherited, autosomal dominant disorder that characteristically affects the jaws of children. The disease typically manifest as a bilateral swelling with associated submandibular lymph node enlargements and usually regresses as age advances. The disease is microscopically indistinguishable from other giant cell lesions and is essentially a clinical diagnosis. The association of cherubism with gingival fibromatosis, epilepsy, mental retardation, stunted growth, and hypertrichosis is referred as Ramon syndrome. We report a case of Ramon syndrome in an 8 year old girl.

Abstract
We report on a patient with congenital generalized hypertrichosis, mental retardation, tonic-clonic seizures with onset during the first year of life and gingival overgrowth, unrelated to antiepileptic treatment. This phenotype represents a unique combination of features, bridging the variable association of gingival overgrowth, generalized hypertrichosis, mental retardation or epilepsy. This may occur in combination with nail and/or digital anomalies, as in Zimmermann-Laband syndrome, and the broader phenotypes of the Anavi, Göhlich-Ratmann and Ramon syndromes. On the basis of the clinical overlap between our patient and these disorders inherited either as autosomal dominant or recessive traits and unknown molecular defects, a recurrence risk of one in four was considered appropriate.

Abstract
Hypertrichosis is hair growth that is abnormal for the age, sex, or race of an individual, or for a particular area of the body. Recognized forms of hypertrichosis are reviewed. Hirsutism, which is male-pattern hair growth in a female or child, is not included in this review. Hypertrichosis is categorized as congenital or acquired, and regional or generalized. Methods of managing hypertrichosis are also briefly reviewed

Abstract
Congenital generalized terminal hypertrichosis is a rare disease, especially when associated with gingival hyperplasia. Congenital hypertrichosis can be a clinical feature of several syndromes, so these patients must be studied by a multidisciplinary team that should include a dermatologist, geneticist, psychologist, odontologist, and an endocrinologist. We report a 7-year-old girl with congenital generalized hypertrichosis and gingival hyperplasia, and analyze the clinical approach, differential diagnosis, and treatment.

Abstract
Hereditary gingival fibromatosis is characterized by varying degrees of attached gingival hyperplasia and may in rare cases present as a feature of a generalized syndrome. It is usually inherited as an autosomal dominant condition though recessive forms are described. The dental and genetic features of an affected brother and sister with a probably unique autosomal recessive hereditary fibromatosis syndrome are presented.

Abstract
Hereditary gingival fibromatosis is a rare condition occurring as an isolated anomaly or as part of a genetic syndrome. The isolated or syndromic disorders are usually inherited in an autosomal dominant manner, but an autosomal recessive form has been suggested. We report on male and female siblings who have gingival fibromatosis in association with specific facial dysmorphism. Their phenotype is depicted and described to document this hitherto unreported autosomal recessive gingival fibromatosis syndrome.

Abstract
Forty-nine cases of isolated familial and idiopathic gingival fibromatoses, consisting of 12 cases from six families and 37 cases of idiopathic gingival fibromatosis, were reviewed. Pedigrees of five families revealed various penetrances and genetic heterogeneity as suggested by the presence of both autosomal dominant and autosomal recessive inheritances. Ultrastructurally, the lesions were composed of fibroblast-like cells and myofibroblast-like cells, with the former being the predominant cell type. The 267 cases of familial and idiopathic gingival fibromatoses were analyzed, and they with or without hypertrichosis, mental retardation, and/or epilepsy. These included 49 cases seen by the authors, 50 cases from the Japanese literature, and 168 cases from non-Japanese literature. Isolated gingival fibromatosis occurred more frequently after age of 12 years (P less than 0.0074). There was no significant difference in age of onset between generalized and localized forms of the idiopathic gingival fibromatosis. Gingival fibromatosis with hypertrichosis and mental retardation and/or epilepsy occurred frequently before 12 years (P less than 0.069). It has been shown that heterogeneity of the gingival fibromatosis is a result of either histologic heterogeneity, genetic heterogeneity, or a combination with other systemic disorders.

Abstract
Hereditary gingival fibromatosis is frequently an isolated condition of little consequence apart from a cosmetic problem and occasional associations with hypertrichosis and/or epilepsy. There are, however, several uncommon or rare eponymous syndromes described in which gingival fibromatosis can be a feature: these include the Zimmermann-Laband, Murray-Puretic-Drescher, Rutherfurd, Cowden and Cross syndromes. This paper describes two siblings with features of the rare Zimmermann-Laband syndrome and discusses the major aspects of this and other eponymous syndromes that may be associated with hereditary gingival fibromatosis.

Abstract
Gingival fibromatosis, a rare but often familial condition, is described in two siblings, associated with mental retardation, epilepsy and hypertrichosis. In one child a maxillary giant-cell tumour was found and excised. It is important to distinguish idiopathic gingival fibromatosis from phenytoin-induced gingival hypertrophy.
