An asymptomatic male individual carrying a 5.72 Mb de novo deletion in 8p23.2‑p23.3: A case report

Numerous rearrangements in the 8p23 chromosomal region have been reported; included in these rearrangements are isolated deletions in this area. Such deletions are associated with a wide range of phenotypic characteristics, including motor impairment, epilepsy, intellectual disability, cardiac defects and seizures. The present study describes the case of a 30-year-old asymptomatic man that carries a de novo deletion in 8p23.2-p23.3. Molecular karyotyping indicated that the detected deletion involves genes that are in the critical region which is hypothesized to be responsible for the phenotypic characteristics associated with such deletions. The normal phenotype of the patient supports the hypothesis that there is incomplete penetrance of 8p23.2-p23.3 deletions.
