Abstract
One of the most challenging areas in pediatric testicular pathology is the appropriate understanding and pathological diagnosis of disorders of sexual development (DSD), and in particular, the issue of gonadal dysgenesis. Here we present the main concepts necessary for their understanding and appropriate classification, with extensive genetic correlations.

Clinical and molecular characterization of a Brazilian cohort of campomelic dysplasia patients, and identification of seven new SOX9 mutations. Genet Mol Biol 2014; 38:14-20. [PMID: 25983619 PMCID: PMC4415563 DOI: 10.1590/s1415-475738120140147] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2014] [Accepted: 08/19/2014] [Indexed: 11/21/2022] Open
Abstract
Campomelic dysplasia (CD) is an autosomal, dominantly inherited, skeletal abnormality
belonging to the subgroup of bent bone dysplasias. In addition to bowed lower limbs,
CD typically includes the following: disproportionate short stature, flat face,
micrognathia, cleft palate, bell-shaped thorax, and club feet. Up to three quarters
of 46, XY individuals may be sex-reversed. Radiological signs include scapular and
pubic hypoplasia, narrow iliac wings, spaced ischia, and bowed femora and tibiae.
Lethal CD is usually due to heterozygous mutations in SOX9, a major regulator of
chondrocytic development. We present a detailed clinical and molecular
characterization of nine Brazilian CD patients. Infants were either stillborn (n = 2)
or died shortly after birth and presented similar phenotypes. Sex-reversal was
observed in one of three chromosomally male patients. Sequencing of SOX9 revealed new
heterozygous mutations in seven individuals. Six patients had mutations that resulted
in premature transcriptional termination, while one infant had a single-nucleotide
substitution at the conserved splice-site acceptor of intron 1. No clear
genotype-phenotype correlations were observed. This study highlights the diversity of
SOX9 mutations leading to lethal CD, and expands the group of known genetic
alterations associated with this skeletal dysplasia.
