Clinical manifestations of seizures always started when ictal discharges were present in outer and heterotopic cortices. [ncbi.nlm.nih.gov]

Only the present case showed the mixture pattern of missense mutation (c. 167G>C) and normal sequence of DCX gene indicating that the present case resulted from somatic mosaicism of de novo DCX mutation. [ci.nii.ac.jp]

• Epilepsy

  Deep brain stimulation of the anterior nuclei of the thalamus has been used for the treatment of refractory epilepsy with good results. [ncbi.nlm.nih.gov]

• Disability

  Abnormal development of the cerebral cortex in humans results in epilepsy, autism, intellectual disability, dyslexia, and other learning disorders, and perhaps some psychiatric conditions as well. [rarediseases.info.nih.gov]

  Some patients, however, have only minor disabilities 5. The majority of band heterotopia syndrome cases have now been attributed to an abnormality of the DCX gene (also known as XLIS gene) located on the long arm of chromosome X. [radiopaedia.org]

  The signs and symptoms can vary from severe intellectual disability and seizures that begin early in life and affect both sides of the brain (generalized seizures) to normal intelligence with seizures occurring later in life and affecting only one side [ghr.nlm.nih.gov]

  The most common clinical manifestations are seizures, intellectual disability, and spastic hemiplegia or diplegia. Treatment of polymicrogyria is supportive. Click here for Patient Education [msdmanuals.com]

• Developmental Delay

  At the age of 1 year the patient had severe developmental delay and epilepsy. Chromosome studies and mutation analysis of the DCX and LIS1 genes gave negative results. [ncbi.nlm.nih.gov]

  Male patients with DCX mutations generally present with the classical type of lissencephaly, severe developmental delay, and intractable epilepsy. However, somatic mosaic mutation of DCX can lead to SBH in males. [ci.nii.ac.jp]

• Multiple Congenital Anomalies

  Baraitser-Winter syndrome (BaWS) is characterized by iris coloboma, ptosis, hypertelorism, and mental retardation; it is a rare multiple congenital anomaly or a mental-retardation syndrome of unknown etiology. [ncbi.nlm.nih.gov]

• Seizure

  At these times, both showed a >50% decrease in seizure frequency and an increase in seizure freedom. Both patients had a depressive syndrome after surgery that responded fully to anti-depressive medication in one patient and partly in the other. [ncbi.nlm.nih.gov]

There are two main types of clinical studies: Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments. [rarediseases.info.nih.gov]
