Comments: The Hb Zürich-Langstrasse mutation [IthaID:970] in the proband was considered a de novo mutation occurring in cis on the βIVS-II-654 [IthaID:211] allele that he inherited from his mother, resulting in a βIVS-II-654/Hb Zürich-Langstrasse genotype, which should be interpreted as a novel β0 mutation.
