Abstract

So-called heterotaxy or isomerism is characterized by abnormal lateralization and malformations of the bodily organs. The mechanism is unclear, although there is growing evidence that ciliary dyskinesia is involved. We reviewed genetic findings from patients with isomerism to determine if affected genes were known to be associated with isomerism and ciliary dyskinesia and determine associations between genotype and clinical findings. We identified patients with isomerism cared for over a 16- year period. Characteristics were compared between those with and without identified mutations. A total of 83 patients with isomerism were identified. Of those who had genotyping, 14/27 had mutations identified, most frequently involving the CFC1 and NODAL genes. Specific mutations were associated with clinical findings, with NODAL mutations often portending need for increased clinical support. Genes associated with isomerism and/or ciliary dyskinesia were identified in the cohort. Specific gene mutations may help predict clinical course.
