Agenesis of the corpus callosum (ACC) is a common brain anomaly with a birth incidence of at least 1 in 4,000. ACC can occur as an isolated malformation or as a component of a syndrome. Here, we report on an autosomal recessive syndrome with ACC, optic coloboma, craniofacial dysmorphism, skeletal

In patients with genetically heterogeneous disorders such as intellectual disability or epilepsy, exome sequencing is a powerful tool to elucidate the underlying genetic cause. Homozygous and compound heterozygous mutations in C12orf57 have recently been described to cause an autosomal recessive

Chromosome analysis in two young patients with multiple congenital anomalies revealed a de novo interstitial deletion of 8q that has not been reported before. The deletions were overlapping by 8.35 Mb (8q24.21q24.23). The clinical features shared by our patients were coloboma, VSD, digital

We report two cases of bilateral asymmetric optic disc coloboma (ODC) in siblings. The index patient is a 9-year-old Nigerian girl with severe cognitive deficit who presented with a poor vision of 3 years' duration. She had a history of childhood febrile convulsions and delayed developmental

Recessive mutations in genes encoding voltage-gated Ca2+ channel subunits alter high-voltage-activated (HVA) calcium currents, impair neurotransmitter release, and stimulate thalamic low-voltage-activated (LVA) currents that contribute to a cortical spike-wave epilepsy phenotype in mice. We now

A mentally and physically retarded 4 1/2 year-old boy with epileptic seizures showed a megalocornea on both sides, a coloboma of the iris in the right eye and a white area at the temporal side of the disc in the left eye. At first a coloboma of the disc was suspected. By further controls at the age

A one-month-old infant boy was examined early in life because his mother had bilateral retinoblastoma and his father had bilateral microphthalmia. The ophthalmologist found his right eye was normal size with a coloboma of the iris, choroid, and retina. The left eye was microphthalmic with a coloboma

WD40 repeat-containing proteins form a large family of proteins present in all eukaryotes. Here, we identified five pediatric probands with de novo variants in WDR37, which encodes a member of the WD40 repeat protein family. Two probands shared one variant and the others have variants in nearby

Aicardi syndrome is a genetic disorder characterized by the triad of infantile spasm in flexion, callosal agenesis and ocular abnormalities (chorioretinal lacunae, coloboma of optic disc). We report a typical case of Aicardi syndrome with all the classical features.

BACKGROUND Encephalocraniocutaneous lipomatosis (ECCL), also known as Haberland's Syndrome, is a sporadically occurring neurocutaneous syndrome with no gender or race predilection. ECCL patients present with a broad spectrum of clinical manifestations, often in a unilateral distribution. The

Baraitser-Winter cerebrofrontofacial syndrome (BWCS) is a rare, autosomal dominant condition that is characterized by intellectual disability, distinctive craniofacial features, structural brain abnormalities, seizures, microcephaly, hearing loss, and ocular colobomas. The first three cases were

We report on an 8-year-old female patient with multiple malformations including bilateral cleft lip and palate, coloboma, and craniosynostosis. She presented with severe intellectual disability, seizures, and gastrointestinal dysfunction. Mitochondrial investigations in a muscle biopsy revealed

Wolf-Hirschhorn syndrome (WHS) is a rare developmental disorder associated with hemizygous deletion of short arm of chromosome 4. Main phenotype characteristics of WHS are: intrauterine growth retardation, mental retardation, typical facial dysmorphism ("Greek warrior helmet"), microcephaly and

BACKGROUND Wolf-Hirschhorn syndrome (WHS) multiple congenital anomalies/mental retardation is caused by partial deletion of the short arm of chromosome 4 and can be considered a contiguous gene syndrome, characterized by typical facial appearance, mental retardation, growth delay, and
