Question 2

What types or variants of Rett Syndrome exist?

Accepted Answer

What are the differences between Classic and Atypical Rett Syndrome?

Classic Rett Syndrome is characterized by a phase of normal development followed by a decline in motor and communication abilities. In contrast, Atypical Rett Syndrome includes clinical features that do not fulfill all the criteria for the classic type. One specific form, known as the preserved speech variant or Zappella variant, may enable some recovery of verbal communication and hand function.

Question 3

What are the signs and symptoms of Rett Syndrome?

Accepted Answer

Signs and symptoms may include:

Loss of purposeful hand skills and repetitive hand movements

Loss of spoken language and communication abilities

Slowed head growth leading to microcephaly

Motor coordination issues and gait abnormalities

Breathing irregularities such as hyperventilation or breath-holding

And other related symptoms

Question 4

What are the causes and risk factors of Rett Syndrome?

Accepted Answer

The primary cause of the disorder is mutations in the MECP2 gene located on the X chromosome. Most of these genetic mutations arise spontaneously (de novo) during conception, while inherited cases are documented but are uncommon. Other factors may also contribute.

Question 5

What is the course or nature of Rett Syndrome?

Accepted Answer

The progression of Rett Syndrome typically follows a series of developmental stages, starting with normal growth and early milestones, followed by a regression phase where functional abilities decline.
