    Abstract:
    CHARGE syndrome is an autosomal dominant disorder characterized by features represented in its acronym: Coloboma, Heart defect, Atresia of the choanae, Retarded growth and development, Genital abnormalities, Ear anomalies/deafness. We report two patients with a diagnosis of typical CHARGE syndrome and one with atypical clinical diagnosis. All the three patients had uni- or bilateral choanal atresia and sensorineural hearing loss. The patients were screened for CHD7 gene mutations. Three novel occurring de novo heterozygous mutations were identified: a mutation in the donor splice site of intron 24, a missense mutation in exon 2 and a deletion in exon 11.
