Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Q: Question: Is hIC2 a novel dosage-dependent regulator of cardiac development located within the distal 22q11 deletion syndrome region?
Answer: Our results demonstrate a novel role for Hic2 in cardiac development. Hic2 is the first gene within the distal 22q11 interval to have a demonstrated haploinsufficient cardiac phenotype in mice. Together our data suggest that HIC2 haploinsufficiency likely contributes to the cardiac defects seen in distal 22q11 deletion syndrome.

A: yes
