Sequence cautioni

The sequence AP002748 differs from that shown. Reason: According to the human genome assembly there is a stop codon in position 577 which is only found in 18% of the world population.

Polymorphismi

About 18% of the world population lack a functional ACTN3 due to a stop codon polymorphism at position 577. The absence of a functional ACTN3 expression is not correlated with a disease state [MIMi:102574].
