Final answer:
Amniocentesis and genetic screening can reveal a defective L1-CAM gene in a fetus. Defects in this gene can lead to a condition called L1 syndrome, which is characterized by a range of neurological problems.
Step-by-step explanation:
Amniocentesis and genetic screening can reveal a defective L1-CAM gene in a fetus. The L1-CAM gene is responsible for the production of a protein involved in cell adhesion and neural development. Defects in this gene can lead to a condition called L1 syndrome, which is characterized by a range of neurological problems.
Symptoms of L1 syndrome can include:
- Cognitive impairment
- Motor function difficulties
- Speech and language delays
- Spasticity or stiffness in the muscles
- Behavioral issues
- Vision problems
Overall, the defects in the L1-CAM gene can disrupt proper brain development and function, resulting in the symptoms observed in L1 syndrome.
