The EEC syndrome: a literature study.

Abstract

Analysis of 230 published cases of the EEC syndrome revealed that, besides the cardinal symptoms (ectrodactyly, ectodermal dysplasia and clefting), lacrimal tract abnormalities and urogenital abnormalities are part of this syndrome. Mental retardation and various abnormalities and dysmorphisms of the ears and face, reported in EEC syndrome, do not really seem to be part of it. Conductive hearing loss is associated with clefting. A score for the severity of symptoms in the EEC syndrome is described, and using this score it appears that isolated cases are generally more severely affected than familial cases. We did not find signs of genomic imprinting or anticipation in published EEC families. We did find, however, that interfamilial variability is significantly larger than intrafamilial variability, pointing to genetic (allelic?) heterogeneity. The penetrance of the EEC-mutation is estimated to be between 93% and 98%.

De novo proximal duplication of 1(q12q22) in a female infant with multiple congenital anomalies.

Reports of small proximal 1q duplications are rare. We report a 1 month-old female who was referred to clinic because she was believed to have features suggestive of Turner syndrome. The patient's dysmorphic features included a prominent nose, low-set and crumpled ears, slightly high palate, short neck, high-pitched cry, mild micrognathia, hypoplastic labia majora, and somewhat deep palmar creases. Traditional G-band chromosome studies of the patient were interpreted as 46,XX,dup(1)(q12q21). To further evaluate the extent of the chromosome 1 duplication, Spectral Karyotyping and a series of six fluorescence in situ hybridization (FISH) probes were utilized. The FISH probes refined the extent of the duplication to involve the region 1(q12q22) indicating the duplicated segment was larger than interpreted by the G-banding studies. This first case of non-mosaic proximal duplication of 1q to be characterized by multiple locus specific FISH probes should allow a more refined delineation of the phenotypic findings and clinical significance associated with this rare chromosomal duplication.

Long-term follow-up of a 26-year-old male with duplication of 16p: clinical report and review.

We report on a 26-year-old male with profound psychomotor retardation and a pattern of dysmorphic features and malformations characteristic for duplication of the short arm of chromosome 16. He has an elongated face, sparse hair, upslanting palpebral fissures, anteverted nostrils, hypoplastic thumbs on both hands, and dislocation of several joints. His chromosome aberration was diagnosed at birth and was due to an unbalanced segregation of a maternal translocation t(2;16)(q36;p11). At 26 years of age he is, to the best of our knowledge, the oldest patient with duplication of 16p reported to date. We present a long-term observation of growth, psychomotor development, dysmorphic features and evolution of his skeletal and joint defects as well as a review of the literature.
