1/117. Intrachromosomal triplication of 2q11.2-q21 in a severely malformed infant: case report and review of triplications and their possible mechanism.A female fetus with brain malformations, multicystic kidneys, absence of the right thumb, and a posterior cleft of palate was delivered at 32 weeks of gestation. Cytogenetic studies including FISH showed a novel intrachromosomal triplication of the proximal long arm of chromosome 2 (q11.2-q21), resulting in tetrasomy for this segment. The middle repeat was inverted. At least 11 patients with intrachromosomal triplications have been reported, mostly involving chromosome 15q. The mechanism involved in formation of these rearrangements is compatible with U-type exchange events among three chromatids.- - - - - - - - - - ranking = 1keywords = cleft, palate (Clic here for more details about this article) |
2/117. child with velocardiofacial syndrome and del (4)(q34.2): another critical region associated with a velocardiofacial syndrome-like phenotype.We report on a child with congenital heart disease (atrial septal defect, ventricular septal defect, pulmonic stenosis), submucosal cleft palate, hypernasal speech, learning difficulties, and right fifth finger anomaly manifestations, consistent with velocardiofacial syndrome (VCFS); however, cytogenetic analysis demonstrated a small terminal deletion of the segment 4q34.2 to 4qter. Fluorescent in situ hybridization did not identify a deletion of the critical region associated with VCFS. In previously reported 4q deletions with a breakpoint distal to 4q34.2, no cardiac defects or cleft of palate were reported. Our patient has a deletion of 4q34.2 to 4qter and has palate and cardiac involvement and minor learning difficulties, which implies that genes involved in heart and palate development lie distal to 4q34.2, and that the critical region for more severe mental retardation on 4q may reside proximal to 4q34.2. These results suggest that a distal 4q deletion can lead to a phenotype similar to VCFS and emphasizes the importance of searching for other karyotype abnormalities when a VCFS-like phenotype is present and a 22q deletion is not identified.- - - - - - - - - - ranking = 5.3982312730936keywords = cleft palate, cleft, palate (Clic here for more details about this article) |
3/117. Case of partial trisomy 9p and partial trisomy 14q resulting from a maternal translocation: overlapping manifestations of characteristic phenotypes.We report on a female infant with partial trisomy 9p (pter-->p13) and partial trisomy 14q (pter-->q22) resulting from a 3:1 segregation of a maternal reciprocal translocation (9;14)(p13;q22). Both trisomy 9p and partial trisomy 14q have been described as recognized phenotypes with characteristic patterns of anomalies. This patient appears to be the first reported with a partial duplication of both 9p and 14q resulting in an overlapping phenotype including minor facial anomalies, cleft palate, and hand-foot anomalies. However, the facial findings were more pronounced than commonly observed in cases with only one or the other duplicated chromosome regions, resulting in a distinctive appearance.- - - - - - - - - - ranking = 3.6123138014795keywords = cleft palate, cleft, palate (Clic here for more details about this article) |
4/117. cleft palate, ptosis, digital anomalies and mental retardation: a new syndrome or a distal arthrogryposis variant?A case is presented of a female with cleft palate, digital anomalies and mental retardation. The case is compared with one already reported and possible diagnoses discussed.

5/117. X-linked mental retardation syndrome with short stature, small hands and feet, seizures, cleft palate, and glaucoma is linked to Xq28.Of the gene-rich regions of the human genome, Xq28 is the most densely mapped. Mutations of genes in this band are responsible for 10 syndromal forms of mental retardation and 5 nonsyndromal forms. Clinical and molecular studies reported here add an additional syndromic form of X-linked mental retardation (XLMR) to this region. The condition comprises short stature, small hands and feet, seizures, cleft palate, and glaucoma. One affected male died at age 19 years in status epilepticus, but others have survived to old age. Carrier females do not have somatic anomalies or mental impairment. The gene is localized to the terminal 8 Mb of Xq28 with markers distal to DXS8011 showing linkage to the disorder with a lod score of 2.11 at zero recombination.- - - - - - - - - - ranking = 18.061569007397keywords = cleft palate, cleft, palate (Clic here for more details about this article) |
6/117. Unknown syndrome in two male sibs with hypotonia, ptosis, hand malformations, 2/3 toes syndactyly, and mental retardation.We report two brothers from nonconsanguineous parents who share hypotonia, ptosis, high arched palate, camptodactyly, fifth fingers clinodactyly, 2/3 toes syndactyly and psychomotor retardation. Differential diagnosis, such as the Ohdo syndrome, the Morillo-Cucci syndrome, the Marden-Walker-like syndrome, and the Frydman syndrome and discussed.- - - - - - - - - - ranking = 0.39295873580708keywords = palate (Clic here for more details about this article) |
7/117. Dominant inheritance of cleft palate with minor abnormalities of hands and feet: a new syndrome?We report a family in which four members of three generations are affected by median cleft palate. The proband and her mother have additional features including bilateral single transverse palmar creases, broad great toes and hypoplastic fifth toenails. Dominant isolated cleft palate has rarely been reported, and there are no previous reports of dominant cleft palate with these associated features. We believe that this represents a previously unreported syndrome, which needs to be considered when assessing recurrence risk for cleft palate.- - - - - - - - - - ranking = 28.898510411836keywords = cleft palate, cleft, palate (Clic here for more details about this article) |
8/117. The Richieri-Costa and Pereira form of acrofacial dysostosis: first case in a non-Brazilian infant.We report on a French boy with cleft mandible, pre/postaxial hand anomalies, and clubfoot born to consanguineous parents. These findings are comparable to those of previous cases of the autosomal recessive Richieri-Costa and Pereira syndrome of short stature, Robin sequence, cleft mandible, pre/postaxial hand anomalies, and clubfoot.

10/117. Two brothers with distal arthrogryposis, peculiar facial appearance, cleft palate, short stature, hydronephrosis, retentio testis, and normal intelligence: a new type of distal arthrogryposis?We report on two brothers, a 22-month-old boy and a 7-month-old boy, with multiple distal arthrogryposis (DA), peculiar facial appearance, cleft palate, short stature, hydronephrosis, retentio testis, and normal intelligence and karyotypes. The parents were cousins once removed. The combination of the clinical manifestations in the patients and the lack of involvement in their parents are incompatible with any known types of DA, and suggest a new type of DA. The parental consanguinity in the family suggests that the disorder is an autosomal recessive condition, although X-linked inheritance is not ruled out.- - - - - - - - - - ranking = 18.061569007397keywords = cleft palate, cleft, palate (Clic here for more details about this article) |
