amelogenesis imperfecta/seizures

We describe an 11-year-old boy with hypoplastic amelogenesis imperfecta, yellow teeth, seizures, and developmental delay, which are the hallmarks of Kohlschütter-Tönz syndrome. Compared to other reported cases of the syndrome, our patient had less severe developmental delay. Also, spasticity and

K(+)-dependent Na(+)/Ca(2+) exchangers belong to the solute carrier 24 (SLC24A1-5) gene family of membrane transporters. Five different gene products (NCKX1-5) have been identified in humans, which play key roles in biological processes including vision, olfaction, and skin pigmentation. NCKXs are

Kohlschütter-Tönz syndrome is a central nervous system (CNS) degenerative disease with convulsions and mental regression in which the affected children present with yellow teeth due to defective enamel. We present a family in which 2 affected children (a boy and a girl) were born to consanguineous

OBJECTIVE Kohlschutter-tonz syndrome (KTS) is a rare neurodegenerative disorder that presents with seizures, developmental regression, characteristic hypoplastic dental enamel indicative of amelogenesis imperfecta and dysmorphologies. Genetic analysis has identified loss-of-function mutations within

Kohlschutter syndrome is a rare neurodegenerative disorder presenting with intractable seizures, developmental regression and characteristic hypoplastic dental enamel indicative of amelogenesis imperfecta. We report a new family with two affected siblings.

BACKGROUND Kohlschütter-Tönz syndrome is a rare neurodegenerative disorder presenting with intractable seizures, developmental regression, and characteristic hypoplastic dental enamel indicative of amelogenesis imperfecta. Recently, mutations in ROGDI were identified in part of Kohlschütter-Tönz

Kohlschütter's syndrome is a combination of amelogenesis imperfecta, progressive mental retardation and epileptic seizures. We report on a patient with typical signs of this syndrome. Beneath severe enamal defects of teeth, the patient has been suffering from progressive mental and motoric

Kohlschütter-Tönz Syndrome is a rare disorder clinically characterized by amelogenesis imperfecta, epilepsy and progressive mental deterioration. We present an additional case of this syndrome of a nine year-old boy who was referred by pigmented teeth. The mental deterioration was associated with

Raine syndrome is a rare autosomal recessive bone dysplasia characterized by characteristic facial features with exophthalmos and generalized osteosclerosis. Amelogenesis imperfecta, hearing loss, seizures, and intracerebral calcification are apparent in some affected individuals. Originally, Raine

Kohlschütter-Tönz syndrome (KTS) is a rare autosomal recessive disorder characterized by amelogenesis imperfecta, psychomotor delay or regression and seizures starting early in childhood. KTS was established as a distinct clinical entity after the first report by Kohlschütter in 1974, and to date,

Kohlschutter-Tonz syndrome (KTS) is a rare autosomal-recessive disorder of childhood onset, and it is characterized by global developmental delay, spasticity, epilepsy, and amelogenesis imperfecta. In 12 KTS-affected individuals from a Druze village in northern Israel, homozygosity mapping localized

BACKGROUND Kohlschutter-Tonz syndrome (KTS; MIM 22675) is a rare autosomal recessive disorder characterized by intellectual impairment, spasticity, epilepsy, and amelogenesis imperfecta. We have recently identified the causative gene and mutation underlying KTS, namely, p.R157X, corresponding to
