Adams-Oliver syndrome: Case report

Introduction. Adams-Oliver syndrome is characterized by congenital aplasia of the vertex skin of the skull in combination with skull and transverse limb defects. Case Outline. We presented a 5-month old female infant with Adams-Oliver syndrome manifested as cutis marmorata, dilated scalp veins and limb reduction defects. Clinical manifestation also included thumb hypoplasia and extreme hypoplasia of other fingers, with agenesis of all toes on both feet. Echocardiogram revealed foramen ovale apertum. Venography showed dilated malformed scalp and neck veins, predominantly on the right side. On the basis of the clinical features and extended investigation we confirmed Adams-Oliver syndrome in the presented patient. Conclusion. We recommended prenatal diagnosis in case of future pregnancies, ultrasound examination, and follow-up of foetal anomalies

The Impact of the <i>IKBKG</i> Gene on the Appearance of the Corpus Callosum Abnormalities in Incontinentia Pigmenti

Incontinentia pigmenti (IP) is a rare skin disease combined with anomalies of the teeth, eyes, and central nervous system (CNS). Mutations of the IKBKG gene are responsible for IP. Among the most frequent CNS abnormalities found in IP using magnetic resonance imaging (MRI) are corpus callosum (CC) abnormalities. The aim of the study was to determine the presence of CC abnormalities, their relationship with the IKBKG mutations, and the possible presence of mutations of other genes. A group of seven IP patients was examined. Analyses of the IKBKG gene and the X-chromosome inactivation pattern were performed, as well as MRI and whole exome sequencing (WES) with the focus on the genes relevant for neurodegeneration. WES analysis showed IKBKG mutation in all examined patients. A patient who had a mutation of a gene other than IKBKG was excluded from further study. Four of the seven patients had clinically diagnosed CNS anomalies; two out of four had MRI-diagnosed CC anomalies. The simultaneous presence of IKBKG mutation and CC abnormalities and the absence of other mutations indicate that IKBKG may be the cause of CC abnormalities and should be included in the list of genes responsible for CC abnormalities
