To study the phenotypic spectrum and management of holoprosencephaly (HPE), we reviewed the findings of eight children with HPE from 3 to 10 years of age, who underwent intervention programs and rehabilitation at our center. One patient had alobar HPE, three semilobar HPE, and four lobar HPE. All patients had postnatal growth retardation, and seven showed a decreased BMI (< 25% tile). All patients had severe developmental delay and mental retardation (DQ < 40), showing no obvious correlation between their severity and the type of HPE. Neurologically seven patients had spasticity (3 spastic quadriplegia, 2 spastic diplegia, 2 mixed-type), except one patient with a 7q deletion [46,XY,del(7) (q35)] who had generalized hypotonia. Seven had variable types of seizures. All patients had feeding difficulties and were assessed by speech-language therapists. Four patients required tube feeding, four had gastroesophageal reflux disease. Recurrent respiratory tract infection was common. Three patients had abnormal serum sodium concentration (1 diabetes insipidus, 1 idiopathic hypernatremia, 1 hyponatremia). No family history of HPE was elicited. In conclusion, patients with HPE should be followed up closely for complications such as feeding difficulty, malnutrition, seizures, spasticity, infection, and osmoreceptor-hypothalamus-hypophyseal axis abnormalities.

The clinical manifestations and cytogenetic details of a de novo partial deletion of the short arm of chromosome 8, del(8)(p23.1), and inversion of long arm chromosome 7, inv(7)(q11.2q32), are described. The case was a 22 month old girl referred to our cytogenetic laboratory due to many abnormal features such as congenital microcephaly, hypotonia, developmental delay, strabismus, highly arched palate, hypernatremia, hypermagnesemia and deafness. Chromosome analysis revealed 46,XX, inv(7)(q11.2q32),del(8)(p23.1) de novo karyotype. The concurrence of these two abnormalities has not been reported previously.
