Complex toe syndactyly with characteristic facial phenotype: A new syndrome?

Nonsyndromic syndactyly is a common, heterogeneous hereditary condition of webbed fingers and toes that can be cutaneous or bony, unilateral or bilateral. We describe a patient with complex toe syndactyly and oligodactyly, some interesting skeletal hand findings and atypical facial features without other case like this described before. Cenani-Lenz syndrome (CLS) is a rare disorder with total syndactyly and irregular synostosis of carpal, metacarpal and phalanges, it may involve ulna and radius and digital rays may be absent, some of these were described with atypical facial features and one patient had renal hypoplasia and vertebral anomalities but our patient does not have the oligodactyly or syndactyly of the hands that is consistently present in all patients with CLS. the atypical facial features of our patient resemble Kabuki syndrome but oligodactyly and complex Syndactyly have not been described in Kabuki syndrome and this patient has normal intelligence, and extreme eyelid defect (resembling ablepharon). Therefore, for our patient, we suggested to treat in a new condition of limb anomalies and atypical face.

Unusual duplication in the pericentromeric region of chromosome 9 in a patient with phenotypic alterations

Several alterations involving the pericentromeric region of chromosome 9 are considered as normal population variants. These heterochromatic variants or heteromorphisms can include 9qh+, 9cen+, 9ph+, 9ph-, inv(9)(p11q13), and other patterns which can only be defined by FISH studies. However, some heteromorphisms have been found more frequently in patients with several clinical disorders. Here, we report on a patient with intellectual disability, language and neurodevelopmental delay, as well as facial dysmorphism and an unusual chromosome 9. While the banding karyotype was indicative of a simple pericentric inversion of one chromosome 9 [46, XX, inv(9)(p12q13)], array comparative genomic hybridization showed a 6-Mb duplication, including 22 genes: arr[hg19] 9p13.1p11.2(38,869,901-44,870,714) x3 dn. Molecular cytogenetics using a panel of probes specific for the pericentromeric region of chromosome 9 showed an unusual, rearranged chromosome 9, der(9)(pter -> p11.2Sao Paulo Research Foundation (FAPESP), Brazil [2014/11572-8]Genetics Division, Department of Morphology and Genetics, Universidade Federal de São Paulo, São Paulo, BrazilInstitut für Humangenetik, Universitätsklinikum Jena, Jena, GermanyGenetics Division, Department of Morphology and Genetics, Universidade Federal de São Paulo, Rua Botucatu 740, BR-04023900 Sao Paulo, SP, Brazil.FAPESP: 2014/11572-8Web of Scienc
