Testis development in the absence of SRY: chromosomal rearrangements at SOX9 and SOX3.

Duplications in the ~2 Mb desert region upstream of SOX9 at 17q24.3 may result in familial 46,XX disorders of sex development (DSD) without any effects on the XY background. A balanced translocation with its breakpoint falling within the same region has also been described in one XX DSD subject.

Constitutional ring chromosome 11 mosaicism in a Wilms tumor patient: Cytogenetic, molecular and clinico-pathological studies.

We report on a boy with three cell lines: 46,XY, r(11)(p15.5,q25)[90]/45,XY,-11 [8]/47,XY, r(11)(p15.5,q25)x2[2], with minor anomalies and mental retardation who developed asynchronous bilateral Wilms tumors (WTs).

Shprintzen-Goldberg omphalocele syndrome: a new patient with an expanded phenotype.

Shprintzen and Goldberg [1979] described a new autosomal dominant syndrome characterized by omphalocele, scoliosis, pharyngeal and laryngeal hypoplasia, mild dysmorphic face, and learning disabilities. This condition was described in a father and three daughters, one of whom died in infancy, probably of airway narrowing. Here, we report on a second observation of this syndrome in a 6-year-old patient.
