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.
