The Galloway-Mowat syndrome, a rare inherited disorder, is characterized by congenital microcephaly with various neurological abnormalities and early onset of nephrotic syndrome with unresponsiveness to treatment, progressive deterioration in renal function and death in early lifetime. In this report, we describe a girl with microcephaly, seizures. and psychomotor retardation who developed nephrotic syndrome at 17 months of age.

We report on two Korean siblings with multiple congenital anomalies : microcephaly, gyral abnormality, minor facial anomalies, and congenital nephrotic syndrome. The first infant developed proteinuria at age 3 days. This condition appeared similar to that described by Galloway and Mowat and reviewed by Cooperstone, et al, especially the presence of abnormal gyral patterns. She died at 19 months. The second infant; the brother of the first baby had a very similar condition. These two cases may represent the first cases of Galloway-Mowat syndrome in the Korean population.

Seckel syndrome is a rare autosomal recessive disease. The characteristic features of Seckel syndrome include Intrauterine and postnatal growth deficiency, severe microcephaly, and a bird-like head. General appearance of our patient was characterized by Pre- and postnatal growth retardation, microcephaly, large eye, and a beaked nose. The patient had mental retardation with CNS anomalies. The CNS anomalies seen in the patient included cerebral dysgenesis and cerebellar atrophy. So, we report the case of CNS anomalies in Seckel syndrome.

OBJECTIVE: To explore the clinical characteristics and genetic mutation in a family affected with Seckel syndrome. METHODS: Clinical data of the proband and his family members were collected. Potential mutations were detected by high-throughput sequencing and Sanger sequencing. RESULTS: The proband, a 7-year-and-3-month-old boy, has featured proportioned dwarfism, microcephaly, "bird head" appearance (narrow and backward forehead, prominent and protruded eyes, beak-shaped nose and microretrognathia), high-arched palate, enamel dysplasia, hypodontia, and mental retardation. His parents and two sisters were all phenotypically normal. The proband was found to harbor compound heterozygous c.1535T>A (p.L512X) and c.3346-5T>C (splicing) mutations of the CEP152 gene, which were respectively inherited from his mother and father. CONCLUSION The clinical features and genetic mutation of a case with Seckel syndrome were delineated. The newly discovered mutations have expanded the spectrum of CEP152 gene mutations.

Cases of interstitial deletions of the long arm of chromosome 17 are very rare, with only nine cases ever reported worldwide. We describe a 12-year-old boy with profound developmental delay, microcephaly, facial dysmorphism, contracture of the large joints and bilateral hearing loss. A chromosomal study using a peripheral blood sampled revealed 46,XY,del(17)(q22q23). To our knowledge, he is the first case of interstitial deletion of the long arm of chromosome 17 ever reported in Korea.

Most cases of microcephaly with growth failure and developmental delay have a genetic or metabolic etiology. Whole-exome sequencing (WES) has uncovered many causative genes and has also broadened their phenotypic spectrum. The present study applied WES to a boy with microcephaly, growth failure, developmental delay, seizures and atopic dermatitis, which reveal an unexpected frame-shift mutation (c.1248_1253delinsCT, NM_014009.3; p.Lys416Asnfs, NP_054728.2) in the forkhead box P3 gene (FOXP3). Mutations of this gene are known to result in immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome. Mutation of FOXP3 was reverified by Sanger sequencing in the proband and his carrier mother. Flow-cytometry expression study of FOXP3 in peripheral white blood cells showed that the mean fluorescence intensity of FOXP3 was lower in the proband than in a normal control. We report a mild form of IPEX syndrome without chronic protracted diarrhea or major infections, instead presenting with proportional microcephaly, growth failure, developmental delay, seizures and atopic dermatitis.

Xeroderma pigmentosum is autosomal recessive, degenerative disease generated by abnormal repair of DNA damaged by ultraviolet radiation and environmental mutagens. DeSanctis-Cacchione syndrome is the most severe form of xeroderma pigmentosum variant. This syndrome is characterized with microcephaly, progressive mental retardation and deterioration, retarded growth and sexual development, sensorineural deafness, and cerebellar ataxia, choreoathetsis, quadriparesis. We describe the case of a 17 year old female patient, which fits into Desanctis-Cacchione syndrome clinically.
