Carlotta is 2 years old and is Edoardo’s younger sister. She was diagnosed with Tango2 when she was 1 year old. So far she has no evident symptoms.
Carlotta started crawling at 8 months and walking at 15 months. She luckily has never had rhabdomiolysis.
She is very shy and gets frustrated easily if she cannot do things. She is very attached to her brother and tries to help him in his daily activities. From the cognitive point of view, she understands everything but she is very delayed in her verbal communication. She can only say a few words. We think this is part of the delay most tango2 children present with, but we do not know how she will evolve.
