Lissencephaly, which literally means “smooth brain,” is a rare, gene-linked brain malformation characterized by the absence of normal convolutions (folds) in the cerebral cortex and an unusually small head (microcephaly). Among the genetic variations that can lead to lissencephaly, mutations in the DCX (Doublecortin) gene are significant, especially in causing X-linked lissencephaly and subcortical band heterotopia (SBH), conditions that affect neuronal migration during the early stages of fetal brain development. DNA Labs UAE offers a comprehensive genetic test for the DCX gene, helping in the diagnosis of these conditions.
Symptoms of DCX Gene Lissencephaly/Subcortical Laminal Heterotopia X-linked
The symptoms associated with DCX gene mutations largely depend on the severity of the brain malformations. In general, individuals with lissencephaly exhibit a range of neurological and developmental challenges, including:
- Severe intellectual disability: Most affected individuals face significant learning difficulties and cognitive impairments.
- Motor skill development issues: Delays in sitting up, crawling, and walking are common due to poor muscle tone and coordination.
- Epilepsy: A high prevalence of seizure disorders is observed, often starting in infancy and varying in severity.
- Feeding difficulties: Problems with sucking or swallowing can lead to poor nutrition and growth.
- Respiratory problems: Complications in breathing may occur, sometimes leading to life-threatening conditions.
- Microcephaly: A notably smaller head size is a hallmark of lissencephaly, reflecting the underlying brain growth issues.
For females carrying a mutation in the DCX gene, the manifestation might be less severe, often presenting as subcortical band heterotopia (SBH), also known as “double cortex” syndrome. Individuals with SBH typically have better outcomes but may still experience mild to moderate intellectual disability and epilepsy.
DCX Gene Lissencephaly/Subcortical Laminal Heterotopia X-linked Genetic Test
Understanding the genetic underpinnings of lissencephaly and SBH is crucial for accurate diagnosis, management, and genetic counseling. DNA Labs UAE offers a specialized genetic test targeting the DCX gene mutations associated with these conditions. This test is a valuable tool for confirming a diagnosis, especially in cases where the clinical presentation is suggestive of a DCX gene-related disorder.
The test process is streamlined and designed for patient convenience. A simple blood sample is all that’s required to conduct the analysis. The laboratory utilizes advanced sequencing technologies to identify mutations in the DCX gene that are indicative of lissencephaly and SBH.
The cost of the DCX gene lissencephaly/subcortical laminal heterotopia X-linked genetic test is 4400 AED. While the cost may seem significant, the insights provided by this test can be invaluable for affected families. It not only aids in the diagnosis but also helps in planning the management of the condition and understanding the risk of recurrence in future pregnancies.

Early diagnosis and intervention are key to managing the symptoms associated with DCX gene mutations. With the support of genetic testing, families can gain insights into their condition and access tailored support and treatments that can significantly improve the quality of life for those affected.
