[Identification of a recurrent mutation in the ROR2 gene in a Chinese family with brachydactyly type B].

OBJECTIVE: To identify the disease-causing mutation in a Chinese family with brachydactyly type B (BDB). METHODS: Genomic DNA was extracted from peripheral blood samples of family members. Exons 8 and 9 of the ROR2 gene were amplified by polymerase chain reaction (PCR) and sequenced directly. Furthermore, the PCR products showing mutation were cloned into pMD18T vector and the insert fragments were sequenced. RESULTS: A 1398-1399 insA heterozygous mutation was detected in the patient. This mutation had been found in German families with BDB. CONCLUSION: To the authors' knowledge, it is the first report on identification of the ROR2 pathogenic mutation in Chinese patients with BDB.

Molecular genetic characterization of a Korean split hand/split foot malformation (SHFM).

Split hand/split foot malformation (SHFM; ectrodactyly) is genetically heterogeneous, with mutations identified at five loci (SHFM1 at 7q21.3, SHFM2 at Xq26, SHFM3 at 10q24, SHFM4 at 3q27 and SHFM5 at 2q31). In this study, we attempted to identify and localize the causative allele of a Korean case of SHFM. Pedigree analysis showed that the Korean SHFM was autosomally dominant and its penetrance was high, indicating that it was not caused by SHFM2. Clinical features were variable, but limited to the four limbs unlike SHFM1, SHFM4 and SHFM5. G-banding and FISH failed to identify any chromosomal abnormalities. We also performed mutation screening by SSCP and DNA sequencing, as well as loss of heterozygosity (LOH) analysis, to exclude the possibility that SHFM4 or SHFM5 were involved; these revealed no mutations in gene p63 and no LOH on 2q31, respectively. It therefore appears that the Korean SHFM may be caused by mutation of SHFM3. In fact, linkage analysis using informative microsatellite markers indicated that SHFM3 was linked to D10S577 with a maximum LOD score of 1.15 at recombination fraction zero. Finally, we identified two novel alleles (191 and 211 bp) of D10S577 that have not been found in Western populations.

[DOOR (deafness, onychodystrophy, osteodystrophy, mental retardation) syndrome].

Authors highlight the difficulties of syndrome identification through reporting the first case of DOOR syndrome in Hungary (the 28th case worldwide). The awareness and appropriate weighing of the importance of vestigial nails (onychodystrophy) was crucial for the correct diagnosis. Based on the normal level of 2-oxoglutarate excretion, the patient can be categorized as type 2. This is associated with better survival, which does not mean a substantial difference in quality of life. Although, prenatal diagnosis is not possible at present, knowledge of the enzyme defect and detection of the reduced activity of the 2-oxoglutarate dehydrogenase E1 component may provide an opportunity. If parents opt to have another child, a 25% risk is to be taken into account.

Short stature, pulmonary hypertension, sclerodactyly-like involvement and dysmorphic appearance: a newly described syndrome?

We report a 21-year-old woman who has moderate to severe pulmonary hypertension, short stature, dysmorphic appearance, lipodystrophy and sclerodactyly-like involvement of her extremities. Cognitive development is in the low-average range. Various diagnoses have been suggested over the years, but none seem to fit her clinical presentation exactly. We suggest that she may have a previously undescribed connective tissue disorder with primary pulmonary involvement.

Orthopedic aspects of the Marfan phenotype.

Thirty-six patients with the phenotypic features of Marfan's syndrome (arachnodactyly, abnormal ratio of arm span to height, ligamentous laxity, and tall stature) were evaluated and classified into three groups. Group 1 represented definite Marfan's syndrome and included patients with two or more major signs, with additional minor signs as described by McKusick (18 patients). Group 2 represented probable Marfan's syndrome and included patients with one major sign and multiple minor signs (nine patients). Group 3 represented the Marfan phenotype and included patients with multiple minor signs (nine patients). A high incidence of scoliosis occurred in all groups (100% in Group 1 and 89% in Groups 2 and 3 combined). Group 1 patients had longer, multiple, and more progressive spinal curves. Protrusio acetabuli (Type II and III hips) was present in 22 patients (11 in Group 1, six in Group 2, and five in Group 3), with more severe involvement noted in Group 1. Foot deformities of varying types and severity occurred in all groups but were seen most often in Group 1 patients. Patients with the features of Marfan's syndrome (even without major diagnostic criteria) have a high incidence of progressive scoliosis, protrusio acetabuli, and foot deformities.

[Report of a rare distal arthrogrophy large family].

We describe a seven-generation large family with talipomanus and talipes, 175 individuals in this family were involved. 32 affected individuals including 18 males and 14 females whose clinical features were different and 1 suspicious male were found. The talipomanus were symmetrical, and varus and valgus were caused by vertical talus. We investigated their living environment, the dietary habit, obstetrical history, physical status, lifespan, and studied cytogenetics and so on. We propose these defects were rare distal arthrogrophy genetic disease.

The facio-audio-symphalangism syndrome in a four generation family with a nonsense mutation in the NOG-gene.

We report a four generation family with features of the facio-audio-symphalangism syndrome. This condition is characterized by proximal symphalangism, conductive hearing loss due to stapes fixation and a distinctive facies. A novel nonsense mutation in the NOG gene on chromosome 17q22 was identified in the patients. The variable expression and progressive nature of the syndrome is well illustrated by this family. The role of Noggin as the causative factor of symphalangism is discussed.
