Methods and compositions for treating cornelia de lange syndrome
View Patent ↗Disclosed are methods and compositions for treating subjects with Cornelia de Lange Syndrome (CdLS). Specifically disclosed are methods for using Indomethacin or Acemetacin to treat subjects with CdLS. Also disclosed are methods for identifying compounds beneficial for the treatment of CdLS using an assay based on the expression of NIPBL or NIPBL homologous or orthologous genes. Also disclosed is a method of identifying compounds beneficial for the treatment of CdLS based on administering a test compound to Drosophila lava with reduced expression of Nipbl, and determining the normalization of CdLS phenotypes.
1. A method of treating Cornelia de Lange Syndrome (CdLS) in a subject comprising, administering an effective amount of Indomethacin or Acemetacin to the subject, wherein cellular expression levels of NIPBL or NIPBL homologous or orthologous mRNA are increased.
2. The method of claim 1 , wherein the subject is a human and expression levels of NIPBL mRNA are measured in blood cells.
3. The method of claim 1 wherein the subject is an adult human and the effective amount is about 150 mg to about 200 mg administered orally per day.
4. The method of claim 1 wherein the subject is a pediatric human and the effective amount is a daily dose of 2 to 4 mg administered orally.
5. The method of claim 1 wherein the subject is a human, and the effective amount is an intravenous dose from about 0.1 mg/kg to about 0.25 mg/kg, per day.
6. The method of claim 1 wherein, the effective amount of Indomethacin or Acemetacin is administered, for an effective treatment period, wherein the symptoms of CdLS are improved.
7. The method of claim 6 wherein the effective treatment period comprises a juvenile period for the subject.
8. The method of claim 6 wherein the subject is a human and the effective treatment period begins before or just after birth.
9. The method of claim 6 wherein the subject is a human and the effective treatment period begins just after a diagnosis of CdLS.
10. The method of claim 6 wherein the subject is a human and the effective treatment period comprises a period of time from a few weeks after birth until 20 years of age.
11. The method of claim 6 wherein the subject is a human and the effective treatment period comprises a period of time from a few weeks after birth until 10 years of age.
12. The method of claim 6 wherein the subject is a human and the effective treatment period comprises a period of time from a few weeks of age until 5 years of age.
13. The method of claim 6 wherein the subject is a human and the effective treatment period comprises a period of time from a few weeks of age until 2 years of age.
14. The method of claim 6 wherein symptoms are selected from the group consisting of reduced growth, behavior, autism rating, cardiac abnormalities, gut abnormalities, kidney structural abnormalities, blood platelet counts, and reduced cognitive function.
15. The method of claim 1 wherein the subject is a mammal and the effective amount is a daily dose of about 2.4 mg administered orally.
16. The method of claim 1 wherein the subject is an adult human and the effective amount is a daily dose of about 25 mg every 8 to 12 hours administered orally.
17. The method of claim 16 wherein the effective amount is increased by 25 mg or 50 mg increments every week to a maximum daily dose of about 150 to about 200 mg.
18. The method of claim 1 wherein the subject is a pediatric human and the effective amount is a daily dose of about 50 mg every 8 to 12 hours given rectally.
19. A method of treating Cornelia de Lange Syndrome (CdLS) in a subject comprising, administering an effective amount of Indomethacin or Acemetacin to the subject, for an effective treatment period, wherein cellular expression levels of NIPBL or NIPBL homologous or orthologous mRNA are increased.
20. The method of claim 19 wherein, the effective treatment period consists of a period comprising a few weeks after birth up to young adulthood of the subject, and wherein the symptoms of CdLS are improved.
