The study of the neurobehavioral consequences of mutations of FMR1, the gene responsible for fragile X syndrome (FraX), has been based largely on correlations between mutation patterns and cognitive profile. Following the characterization of FMRP, the FMR1 gene product, preliminary correlations betw

✦ Synopsis
Trisomy 22 was detected in a 32-week-old fetus born to an overweight mother with hypertension. Severe intrauterine growth retardation was associated with phenotypic manifestations of Fryns syndrome: diaphragmatic hernia, facial defects, and nail hypoplasia with short distal fifth phalanges. This is the second report of congenital diaphragmatic hernia in trisomy 22. This case demonstrates the importance of karyotyping malformed fetuses or newborns, even if a nonchromosome syndrome seems identifiable on clinical grounds. To date, at least 10 cases of Fryns syndrome have been reported without chromosome analysis.

I have read with great interest the paper by Crowe et al. [1997]. It is an excellent clinical and cytogenetic review of trisomy 22 in its various manifestations. I only wish to point out that the first proven case (by G-banding) of trisomy 22 appeared in 1973, in a paper in which we demonstrated the
In a case of mosaic trisomy 22 the trisomic cells were detected primarily in fibroblasts. Results of initial lymphocyte chromosome analysis were normal. However, mosaicism was suspected because the patient had hypomelanosis of Ito, hemiatrophy, failure to thrive, and mental retardation. Mosaicism wa
The tricho-dento-osseous (TDO) syndrome demonstrates kinky curly hair, thin-pitted enamel, taurodontism, and thickening of cortical bone. The purpose of this investigation was to characterize the phenotypic variation of TDO in 3, previously unreported, kindreds and to examine possible candidates for
22q11 deletion syndrome (22qDS) is due to microdeletions of chromosome region 22q11.2. Little is known about the phenotype of adults. We reviewed available case reports of adults (age ≥18 years) with 22qDS and compared the prevalence of key findings to those reported in a large European survey of 22
We report on a girl with Floating-Harbor syndrome, trigonocephaly due to metopic suture synostosis, preauricular pit, hypoplastic thumb, subluxated radial head, and Sprengel deformity. A review suggests that trigonocephaly may be an important craniofacial manifestation in this syndrome that is recog
