Neurogenic Tests - PTEN (Autism with Macrocephaly and Macrosomia)
Steps Involved in IVF:
Procedure Description
PTEN genetic testing has emerged as a critical tool in diagnosing and understanding neurodevelopmental disorders, particularly Autism Spectrum Disorder (ASD) associated with macrocephaly (abnormally large head size) and macrosomia (overgrowth). PTEN stands for “phosphatase and tensin homolog,” a tumor suppressor gene that regulates cell division and growth. Mutations in the PTEN gene can result in conditions that include increased risk of cancer, developmental delays, and physical abnormalities such as macrocephaly and macrosomia, often seen in individuals with ASD.
Children with macrocephaly and macrosomia, coupled with ASD characteristics, are often tested for PTEN mutations to confirm the diagnosis. PTEN testing identifies genetic mutations that can explain the presence of these physical traits and their connection to neurodevelopmental issues, including autism. Individuals with mutations in the PTEN gene are classified within a condition known as PTEN hamartoma tumor syndrome (PHTS), which affects not only cognitive development but also increases cancer risks.
The PTEN test is a neurogenic test that involves collecting a DNA sample, typically from a blood draw or saliva swab, followed by laboratory analysis to check for abnormalities in the PTEN gene. The results provide critical information about whether a PTEN mutation is present, guiding healthcare professionals in formulating an appropriate treatment or monitoring plan, especially in children at risk for neurodevelopmental and oncological issues.
While PTEN mutations are rare, they offer insight into tailored interventions and monitoring for patients with ASD and physical growth abnormalities. Genetic counseling is recommended for families, providing an understanding of the hereditary nature of PTEN mutations and possible future implications.
Procedure Duration
The process of undergoing a PTEN neurogenic test, from sample collection to obtaining results, is relatively straightforward but involves various stages. The first step is the collection of a biological sample, either through a simple blood draw or a saliva swab, depending on the testing facility’s requirements. This initial phase is typically quick, requiring less than an hour for the patient to provide the necessary sample.
Once the sample is collected, it is sent to a specialized laboratory for genetic analysis. This phase can take several weeks to complete, as advanced technologies such as next-generation sequencing are used to detect any mutations in the PTEN gene. The lab must carefully examine the sample for even minute changes in the DNA that could signify a PTEN mutation, which requires precision and time.
After the analysis, results are typically provided within 3-4 weeks. Once the results are delivered, they must be interpreted by a geneticist or other healthcare professional with expertise in neurodevelopmental disorders. This interpretation phase is crucial, as it informs the next steps, which may involve further monitoring, counseling, or personalized treatment plans. It is essential to note that while the test itself does not require a long recovery period, the patient’s family may need time to understand the implications of the results and make decisions about potential treatments and interventions.

Risks & Considerations
- Emotional impact: The results of PTEN testing can be challenging for families, as a confirmed mutation may indicate lifelong developmental challenges and increased cancer risks.
- Inconclusive results: Not all PTEN mutations are well understood, and some results may not provide clear answers, requiring further testing and interpretation.
- Limited availability: PTEN testing is not widely available in all countries, so patients may need to travel or wait for the test.
- Potential cost: Genetic testing can be expensive, especially in countries where it is not covered by insurance or the public healthcare system.
- Cancer risk: The discovery of a PTEN mutation often means that the patient will require long-term cancer screenings and preventive care, adding to the emotional and financial burden for families.
How to Choose the Right Doctor and Hospital
When selecting a doctor or hospital for PTEN testing, it is important to prioritize facilities with expertise in genetic testing and neurodevelopmental disorders. Look for healthcare providers that have experience specifically with PTEN mutations and their associated conditions, including ASD with macrocephaly and macrosomia. A geneticist or neurodevelopmental specialist should be involved in interpreting the test results, as their expertise is crucial for providing an accurate diagnosis and creating an effective treatment or monitoring plan.
Additionally, the hospital or clinic should offer comprehensive genetic counseling services, as this is essential for helping families understand the implications of PTEN mutations and make informed decisions about their child’s healthcare. Finally, choosing a facility that provides ongoing monitoring and support for patients with PTEN mutations, particularly regarding developmental delays and cancer risks, is key to ensuring long-term health outcomes.

Frequently Asked Questions
What actually happens during hyperstimulation of the ovaries?
The patient will take injectable FSH (follicle stimulating hormone) for eight to eleven days, depending on how long the follicles take to mature. This hormone is produced naturally in a woman’s body causing one egg to develop per cycle. Taking the injectable FSH causes several follicles to develop at once, at approximately the same rate. The development is monitored with vaginal ultrasounds and following the patient’s levels of estradiol and progesterone. FSH brand names include Repronex, Follistim, Menopur, Gonal-F and Bravelle. The patient injects herself daily.
What happens during egg retrieval?
When the follicles have developed enough to be harvested, the patient attends an appointment where she is anesthetized and prepared for the procedure. Next, the doctor uses an ultrasound probe to guide a needle through the vaginal wall and into the follicle of the ovary. The thin needle draws the follicle fluid, which is then examined by an embryologist to find the eggs. The whole process takes about 20 minutes.
What happens to the eggs?
In the next step, the harvested eggs are then fertilized. If the sperm from the potential father, or in some cases, anonymous donor, has normal functionality, the eggs and sperm are placed together in a dish with a nutrient fluid, then incubated overnight to fertilize normally. If the sperm functionality is suboptimal, an embryologist uses Intracytoplasmic Sperm Injection to inject a single sperm into a single egg with an extremely precise glass needle. Once fertilization is complete, the embryos are assessed and prepared to be transferred to the patient’s uterus.
How are the embryos transferred back to the uterus?
The doctor and the patient will discuss the number of embryos to be transferred. The number of successfully fertilized eggs usually determines the number of eggs to be placed in the uterus. Embryos are transferred to the uterus with transabdominal ultrasound guidance. This process does not require anesthesia, but it can cause minor cervical or uterine discomfort. Following transfer, the patient is advised to take at least one days bed rest and two or three additional days of rest, then 10 to 12 days later, two pregnancy tests are scheduled to confirm success. Once two positive tests are completed, an obstetrical ultrasound is ordered to show the sac, fetal pole, yolk sac and fetal heart rate.
Embryoscope©
Built into this technology there is a microscope with a powerful camera that allows the uninterrupted monitoring of the embryo during its first hours of life. In this way, we can keep a close eye on the embryo, from the moment when the oocyte is inseminated and begins to divide into smaller and smaller cells, until it can be transferred to the uterus.
