The father was heterozygous for the mutation and the mother did not carry the mutation, as determined by genetic analyses, exome sequencing of parental samples, and a trio\u2010based analysis. Further analysis revealed that the <jats:italic>DYSF<\/jats:italic> gene was not deleted; instead, the entire chromosome 2 of the proband was inherited from the father.
