Insights
Joubert syndrome, a rare genetic disorder, can present with neonatal breathing issues. This study highlights the long-term, progressive psychic and motor improvements observed in two adult siblings with Joubert syndrome.
Area of Science:
- Genetics
- Neurology
- Pediatrics
Background:
- Joubert syndrome is a rare autosomal recessive ciliopathy.
- Characterized by a distinctive cerebellar and brainstem malformation known as the molar tooth sign.
- Often associated with neonatal respiratory dysfunction and developmental delays.
Observation:
- Two siblings diagnosed with Joubert syndrome were followed from infancy to adulthood (26 and 22 years old).
- Initial neonatal period presented with breathing problems of unknown origin.
- Patients exhibited progressive psychic and motor improvement over time.
Findings:
- Both siblings achieved a "borderline" mental level with significant functional independence.
- They possess skills in reading, writing, basic mathematics, and computer use.
- Demonstrated good social integration, independent self-care, and engagement in familial agriculture and recreational activities.
- Normal gait but difficulty running; language is normal though slow.
- Ocular findings included bilateral strabismus in one sibling and unilateral ptosis in the other.
Implications:
- This case series underscores the potential for substantial long-term functional recovery and social adaptation in individuals with Joubert syndrome.
- Highlights the importance of early diagnosis and comprehensive, long-term multidisciplinary care.
- Suggests that despite initial challenges, individuals with Joubert syndrome can achieve a meaningful level of independence and community integration.
Abstract:
We present the case of two siblings with Joubert's syndrome. They had breathing problems of unknown origin during the neonatal period. Their evolution has been followed-up from the first years of age until the present. They are now 26 and 22 years old, respectively. Both patients have a "borderline" mental level, are apparently normal, but have had progressive evolution and psychic and motor improvement. They can read, write and use the four operations in mathematics and can work with the computer. Both siblings are working in the familial agriculture, can play football at an elemental level with other young people of their village, and ride a bicycle and motorcycle. Both patients show normal gait and have difficulty running. Their language is normal, although somewhat slow. They perform their personal self-care that includes independent bathing, independent dressing, independent toileting and independent shaving. Their contact with other people is good. They are shy with women. They manage money. They have good social integration. One patient has bilateral strabismus and the other has unilateral ptosis.
