  • It is caused by a mutation in the JAG1 gene
  • About 50% of ALGS patients have acquired it through a spontaneous mutation
  • ALGS can also be inherited. If one of your parents has ALGS, you have a 50% chance of getting it.
  • Symptoms: yellow skin or eyes, itchy skin, delayed growth, skin bumps, heart murmur

How is Arnatar’s RNA dual modality?

Arnatar’s therapy combines the following:

  • siRNA that silences target mRNAs
  • Antisense oligonucleotides that bind with mRNA and promote protein synthesis.
