Cleft palate, and Febrile seizures

Andersen's syndrome (AS) is a rare disorder characterized by periodic muscle paralysis, prolongation of the QT interval with a variety of ventricular arrhythmias (leading to predisposition to sudden cardiac death) and characteristic physical features: short stature, scoliosis, low-set ears, hypertelorism, broad nasal root, micrognathia, clinodactyly, brachydactyly and syndactyly.

Congenital symmetric circumferential skin creases is characterized by the folding of excess skin, which leads to ringed creases, primarily of the limbs. Affected individuals also exhibit intellectual disability, cleft palate, and dysmorphic features (summary by Isrie et al., 2015). Genetic Heterogeneity of Congenital Symmetric Circumferential Skin CreasesCSCSC2 (OMIM ) is caused by mutation in the MAPRE2 gene (OMIM ) on chromosome 18q12.

Cornelia de Lange syndrome is a clinically heterogeneous developmental disorder characterized by malformations affecting multiple systems. Affected individuals have dysmorphic facial features, cleft palate, distal limb defects, growth retardation, and developmental delay. About 4 to 6% of patients have mutations in the X-linked SMC1A gene, whereas about 60% have mutations in the NIPBL gene (OMIM ) on chromosome 5p13 (CDLS1 ) (summary by Musio et al., 2006, Hoppman-Chaney et al., 2012).For a general phenotypic description and a discussion of genetic heterogeneity of Cornelia de Lange syndrome, see {122470}.

2q32q33 microdeletion syndrome is a recently described syndrome characterized by a variable phenotype involving moderate to severe intellectual deficit, significant speech delay, persistent feeding difficulties, growth retardation and dysmorphic features.

Mowat-Wilson syndrome is an autosomal dominant complex developmental disorder; individuals with functional null mutations present with mental retardation, delayed motor development, epilepsy, and a wide spectrum of clinically heterogeneous features suggestive of neurocristopathies at the cephalic, cardiac, and vagal levels. Mowat-Wilson syndrome has many clinical features in common with Goldberg-Shprintzen syndrome (OMIM ) but the 2 disorders are genetically distinct (Mowat et al., 2003). Goldberg-Shprintzen syndrome is caused by mutation in the KIAA1279 gene (OMIM ) located on 10q.

Early infantile epileptic encephalopathy-54 is a severe neurodevelopmental disorder characterized by delayed psychomotor development, early-onset refractory seizures that are often initially febrile but later afebrile, and severe intellectual disability (summary by de Kovel et al., 2016).

Glycosylphosphatidylinositol biosynthesis defect-17 is an autosomal recessive disorder characterized by variable neurologic deficits that become apparent in infancy or early childhood. Patients may present with early-onset febrile or afebrile seizures that tend to be mild or controllable. Other features may include learning disabilities, autism, behavioral abnormalities, hypotonia, and motor deficits. The phenotype is relatively mild compared to that of other GPIBDs (summary by Nguyen et al., 2018).For a discussion of genetic heterogeneity of GPI biosynthesis defects, see GPIBD1 (OMIM ).

Spastic paraplegia-47 is an autosomal recessive neurodegenerative disorder characterized by neonatal hypotonia that progresses to hypertonia and spasticity and severe mental retardation with poor or absent speech development (summary by Abou Jamra et al., 2011).
