Primary Autosomal Recessive Microcephaly (MCPH) Description

Primary autosomal recessive microcephaly, also known as MCPH, is a rare genetically heterogeneous disorder of neurogenic brain development. It is characterized by reduced head circumference at birth, with variable degrees of mental retardation.

Some people with MCPH may have additional features such as:

• A narrow, sloping forehead
• Mild seizures
• Problems with attention or behavior
• Short stature compared to others in their family

MCPH is a neurodevelopmental disorder that affects the cerebral cortex, and it is considered a prototype of isolated primary (congenital) microcephaly.

Key Features:

• Reduced head circumference at birth
• Variable degrees of mental retardation
• May have additional features such as seizures, attention or behavior problems, and short stature

Based on the provided context, here are the signs and symptoms of primary autosomal recessive microcephaly (MCPH):

• Microcephaly: The head is much smaller than normal, present at birth (congenital) [6]
• Intellectual disability: Most patients have nonprogressive mental retardation [8]
• Delayed speech and language development: Delayed speech and language development are common [3]
• Global developmental delay: Global developmental delay may be present [3]
• Mild seizures: Mild seizures may be present in some cases (10%) [1]
• Short stature: Short stature compared to others in their family is a common feature [1]
• Problems with attention or behavior: Problems with attention or behavior, such as hyperactive behavior, are also common [2]

It's worth noting that these symptoms may vary from person to person and not everyone with MCPH will exhibit all of them.

Diagnostic Tests for Primary Autosomal Recessive Microcephaly

Primary autosomal recessive microcephaly (MCPH) is a rare genetic disorder characterized by a small head size and brain. Diagnostic tests are essential to confirm the condition and rule out other potential causes of microcephaly.

• Head Circumference Measurement: Head circumference measurement is the most common diagnostic tool for MCPH. It involves measuring the distance around the widest part of the head, typically above the eyebrows and ears [2].
• Genetic Testing: Molecular genetic testing can be performed to identify mutations in genes associated with MCPH, such as ASPM, CENPJ, STIL, WDR62, and others [1, 4]. This test is available through various clinical genetic testing services, including PreventionGenetics [4].
• Electroencephalogram (EEG) and Brain MRI: EEG and brain magnetic resonance imaging (MRI) can be performed to evaluate the electrical activity of the brain and detect any abnormalities in brain structure [7].

It's essential to consult with a healthcare professional or a genetic counselor to determine the best diagnostic approach for an individual case. They will consider factors such as family history, clinical presentation, and other relevant medical information.

Unfortunately, there is no specific drug treatment for primary autosomal recessive microcephaly (MCPH). The condition is typically managed through symptomatic care, which may include:

• Physical therapy to improve muscle tone and mobility
• Speech therapy to address communication difficulties
• Anticonvulsants to control seizures, if present

According to search result [5], "There is no treatment for microcephaly that will return the baby's head to a normal size or shape. Microcephaly is a lifelong condition that has no cure."

Search results [7] and [10] also confirm that there is no specific drug treatment available for MCPH.

However, it's essential to consult with a healthcare professional for medical advice and treatment, as they can provide personalized guidance and support for managing the condition. (See search result [8].)

Unfortunately, there are no specific medications or treatments listed in the provided search results that target the underlying genetic cause of primary autosomal recessive microcephaly.

Differential Diagnosis of Primary Autosomal Recessive Microcephaly (MCPH)

Primary autosomal recessive microcephaly (MCPH) is a neurodevelopmental disorder characterized by two principal features: microcephaly present at birth and nonprogressive mental retardation. To distinguish this condition from the many differential diagnoses, it's essential to consider the following:

• Microcephaly without further extracranial malformations: MCPH should be considered in cases where microcephaly is present without other congenital anomalies or facial dysmorphism.
• Diseases associated with primary (congenital) microcephaly: All diseases associated with primary microcephaly, such as Seckel syndrome, should be included in the differential diagnosis of MCPH.

Key Points to Consider:

• Microcephaly is a critical feature of MCPH, and its presence at birth is essential for diagnosis.
• Nonprogressive mental retardation is another key feature of MCPH.
• Differential diagnoses include other conditions that present with microcephaly without extracranial malformations or facial dysm
