ABSTRACT

Waardenburg syndrome [WS] is a rare, autosomal dominant disorder characterized by congenital hearing loss; dystopia canthorum; broad nasal root; depigmantation of hair, skin or both; and heterochromic iris. WS is classified into four types, WS1, WS2, WS3 and WS4. In this paper, we report a new case of Waardenburg syndrome type I in an Iranian female. This report describes a two-year-old female with Waardenburg syndrome type I with features such as unilateral profound sensorineural hearing loss, white forelock, dystopia canthorum, broad nasal root, hypopigmentation of skin and scalp defect. As no treatment is available for patients with WS1, conservative treatments such as skin graft and referral to a hearing specialist are crucial for the normal development of patients

ABSTRACT

Waardenburg syndrome is a rare inherited and genetically heterogenous disorder of neural crest cell development. Four distinct subtypes showing marked interfamilial and intrafamilial variability have been described. We report a girl showing constellation of congenital hearing impairment with 110 dB and 105 dB loss in right and left ear respectively, hypoplastic blue iridis, white forelock, dystopia canthorum and broad nasal root. Other affected relatives of the family, with variable features of the syndrome, have been depicted in the pedigree.

ABSTRACT

Introducción. En 1951 Waardenburg describió un nuevo padecimiento de etiología hereditaria, con características clínicas específicas; a partir de entonces, se han publicado más de 1,500 pacientes similares. Caso clínico. Paciente masculino de 14 años de edad, hijo de padres consanguíneos (primos en primer grado), con antecedentes de retardo en el desarrollo psicomotor. A la exploración física se le encontró: talla de 1.58 m, peso de 81.5 kg; con telecanto, heterocromía de iris, sordera neurosensorial y alteraciones en la pigmentación del pelo, pestañas y cejas. Estudio citogenético: cariotipo en linfocitos de sangre periférica y con técnica de bandas G, sin obtenerse evidencias de alteraciones cromosómicas ni estructurales. Conclusión. A pesar de la existencia de consanguinidad de primer grado en la familiar, la herencia corresponde al tipo I del padecimiento. Además, es necesario realizar como complemento al estudio clínico los marcadores genéticos específicos en todos los casos para identificar la variedad y proceder al asesoramiento genético
