RESUMO
Wolf-Hirschhorn syndrome (WHS) is a syndrome with craniofacial and systemic abnormalities, which is related to 4p deletion. A 3-month old girl with an undiagnosed syndrome was referred for evaluation of the cleft lip and palate. Hypotonia, short stature, cardiac malformation, hypertrophied clitoris, and atypical thumb of both hands was observed. Microcephaly, low-set ear, prominent glabella, downslanting palpebral fissures, a characteristic "Greek warrior helmet" appearance, micrognathia, ears with pits/tags and bilateral incomplete cleft lip apart from incomplete cleft palate were observed as craniofacial findings. With clinical diagnosis of WHS, blood was subjected to karyotyping, which showed a 4p15.2 deletion, consistent with the condition. Here is reported the case of this WHS patient with an uncommon oral cleft extending the phenotypic spectrum of the disorder. The child was referred to a multidisciplinary team to reparative surgery of the cleft lip and palate. The patient is on regular medical follow-up and will be further assisted by dentists, physical therapists, occupational therapists and psychologists. The genotype-phenotype correlation of the affected patient with previous WSH syndrome reports is described.

A síndrome de Wolf-Hirschhorn (WHS) é uma condição genética caracterizada por anomalias craniofaciais e sistêmicas, causada por deleção cromossômica na região 4p. Paciente de 3 meses de idade, gênero feminino, foi encaminhada para avaliação de fissura de lábio e fissura palatina, associada a uma síndrome não diagnosticada. A paciente apresentava-se com hipotonia, baixa estatura, malformação cardíaca, clitóris hipertrofiado e implantação atípica do polegar nas duas mãos. Microcefalia, baixa implantação da orelha, glabela proeminente, inclinação baixa das fissuras palpebrais, aparência característica de capacete de guerreiro grego, micrognatia, fossetas em orelhas, fissura labial bilateral incompleta e fissura palatina incompleta foram observadas como características craniofaciais. Com um diagnóstico clínico de WHS, foi realizado o cariótipo, que mostrou a deleção 4p15.2, consistente com a condição. Esse relato de caso apresenta um caso de WHS, com uma fissura oral incomum, ampliando o espectro fenotípico da doença. A paciente foi encaminhada a tratamento com equipe multidisciplinar para correção cirúrgica da fissura labial e palatina. Encontra-se em acompanhamento médico bem como odontológico, fisioterapêutico e em terapia ocupacional e psicológica. Uma correlação entre genótipo e fenótipo pode ser observada nesse relato da síndrome de WHS.
