SANCHEZ, N.; HERNANDEZ, M.; CRUZ, JP.  y  MELLADO, C.. Phenotypic spectrum of neonatal CHARGE syndrome. Rev. chil. pediatr. [online]. 2019, vol.90, n.5, pp.533-538. ISSN 0370-4106.  http://dx.doi.org/10.32641/rchped.v90i5.1080.

Introduction:

CHARGE syndrome is a genetic disorder of wide phenotypic variability, of autosomal dominant in heritance, caused by pathogenic variants in the CHD7 gene.

Objective:

To describe the broad pheno typic spectrum of neonatal CHARGE syndrome, heterozygous for the CHD7 gene, and the usefulness of genome sequencing in diagnostic confirmation, considering differential diagnoses.

Clinical Case:

34-week preterm newborn, with severe prenatal history of polyhydramnios, increased nuchal trans- lucency, and hyperechogenic cardiac focus, with a TORCH study that ruled out congenital infection. Peripheral facial paralysis, choanal atresia, multiple dysmorphisms, congenital heart disease, and bilateral retinochoroidal coloboma were observed at birth. The neuroimaging study showed hypo plasia of the cochlea and bilateral semicircular canals, and pontocerebellar hypoplasia. The auditory evoked potentials showed deep right-sided sensorineural hearing loss and left anacusis. The patient developed hypocalcemia and immunological alterations, confirming hypoparathyroidism and thy mus hypoplasia. The karyogram was normal and 22q11.2 microdeletion was excluded through mul tiplex ligation-dependent probe amplification (MPLA). A pathogenic variant in the CHD7 gene was detected that confirmed the clinical suspicion of CHARGE syndrome.

Conclusions:

The overlap of clinical characteristics of CHARGE syndrome requires molecular genetic confirmation, considering differences in evolution, therapies, and recurrence risks with other genetic syndromes.
