Abstract
OBJECTIVE Skeletal dysplasia with bowing long bones is a rare group of multiple characterized congenital anomalies. MATERIALS AND METHODS We introduce a simple, practical diagnostic flowchart that may be helpful in identifying the appropriate pathway of obstetrical management. RESULTS Herein, we describe four fetal cases of bent bony dysplasia that focus on ultrasound findings, phenotype, molecular tests, distinctive X-ray features, and chondral growth plate histology. The first case was a typical campomelic dysplasia resulting from a de novo mutation in the SOX9 gene. The second fetus was affected by osteogenesis imperfecta Type II carrying a mutation in the COLA1 gene. The third case was a rare presentation of campomelic dysplasia, Cumming type, in which SOX9 examination was normal. Subsequently, a femoral hypoplasia unusual facies syndrome is also discussed. CONCLUSION Targeted molecular tests and genetic counseling are required for supplementing ultrasound imaging in order to diagnose the correct skeletal disorders.

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.

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.

Abstract
Campomelic dysplasia is a skeletal dysplasia characterized by flat face, Pierre Robin sequence, shortening and bowing of long bones and club feet. The authors describe a case of "acampomelic" campomelic dysplasia that differs from classical campomelic dysplasia by the absence of bone bowing. This condition is among the most common skeletal dysplasias but is often misdiagnosed in the absence of overt campomelia.
