Abstract:
Objective:To study the clinical features, treatment, and prognostic features of Kaufman Oculocerebrofacial syndrome.Methods:The clinical characteristics of a newborn with Kaufman Oculocerebrofacial syndrome admitted to the neonatal unit of Guiyang Maternal and Child Health Care Hospital was reported. Using "Kaufman Oculocerebrofacial syndrome", "Blepharophimosis-ptosis-intellectual disability syndrome" and "UBE3B gene" as keywords, databases including CNKI, VIP database, Wanfang database, Chinese medical journals full-text database, PubMed, Web of Science database and Embase database were searched from the date of establishment to June 2022. The clinical characteristics, treatment and prognosis of Kaufman Oculocerebrofacial syndrome from published literature were summarized.Results:The proband was a boy presenting with small lid fissure, wide eye spacing and feeding difficulties. Whole exome sequencing revealed compound heterozygous mutation in the UBE3B gene, c.1445_1448dupTCAC inherited from his father and c.1703dupA inherited from his mother, both variants had not been reported in the domestic and foreign literature thus far. A total of 34 newborn cases were summarized from 11 case reports, including this report. The main clinical manifestations were developmental delay (35/35), peculiar facial features (35/35), narrow eye slits (35/35), feeding difficulties (33/35), ear abnormalities (33/35), hypotonia (32/35), mouth abnormalities (31/35), breathing difficulties (26/35), small jaws (25/35) and low birth weight (16/35).There is no effective treatment available, and a total of 4 cases followed up to over 16 years old have been reported, all of which have severe mental retardation, language deficiency, along with other serious neurological diseases.Conclusions:when children exhibit symptoms such as narrow eye fissures, feeding difficulties, hypotonia, developmental delays, and peculiar facial features in the neonatal period, whole exome sequence can be used to aid diagnosis and evaluate for Kaufman Oculocerebrofacial syndrome. Families with children of Kaufman Oculocerebrofacial syndrome may undergo prenatal diagnosis based on genetic findings.
