Audrey kicking CASK is about what a sweet, beautiful little girl, and my husband and I go through on a daily basis. Our Audrey has a very rare genetic disorder called CASK gene mutation. This causes intellectual disability, delayed fine and gross motor skills and Microcephaly. Audrey was diagnosed with CASK and Microcephaly at 10 months old. Ever since then, we have been fighting for opportunities to see our baby girl thrive. She is the light of our life, has the sweetest smile and can turn anyone's day around with her contagious giggle.
