Genes associados
1 gene identificado com associação a esta condição. Padrão de herança: Autosomal dominant.
Transcription factor that plays a key role in chondrocytes differentiation and skeletal development (PubMed:24038782). Specifically binds the 5'-ACAAAG-3' DNA motif present in enhancers and super-enhancers and promotes expression of genes important for chondrogenesis, including cartilage matrix protein-coding genes COL2A1, COL4A2, COL9A1, COL11A2 and ACAN, SOX5 and SOX6 (PubMed:8640233). Also binds to some promoter regions (By similarity). Plays a central role in successive steps of chondrocyte
Nucleus
Campomelic dysplasia
A rare, often lethal, osteochondrodysplasia characterized by congenital bowing and angulation of long bones. Other skeletal defects include unusually small scapula, deformed pelvis and spine, and a missing pair of ribs. Craniofacial and ear defects are common. Most patients die soon after birth due to respiratory distress which has been attributed to hypoplasia of the tracheobronchial cartilage and small thoracic cage. Up to two-thirds of affected XY individuals have genital defects or may develop as phenotypic females.

Spatiotemporal Regulation and Lineage Specification in Embryonic Endochondral Ossification.
Long bone formation in vertebrates proceeds via endochondral ossification, a sequential process that begins with mesenchymal condensation, advances through cartilage anlage formation, and culminates in its replacement by mineralized bone. Recent advances in inducible lineage tracing and single-cell genomics have revealed that, rather than being a uniform event, mesenchymal condensation rapidly segregates into progenitor pools with distinct fates. Centrally located Sox9+/Fgfr3+ chondroprogenitors expand into the growth plate and metaphyseal stroma, peripheral Hes1+ boundary cells refine condensation via asymmetric division, and outer-layer Dlx5+ perichondrial cells generate the bone collar and cortical bone. Concurrently, dorsoventral polarity established by Wnt7a-Lmx1b and En1 ensures that dorsal progenitors retain positional identity throughout development. These lineage divergences integrate with signaling networks, including the Ihh-PTHrP, FGF, BMPs, and WNT/β-catenin networks, which impose temporal control over chondrocyte proliferation, hypertrophy, and vascular invasion. Perturbations in these programs, exemplified by mutations in Fgfr3, Sox9, and Dlx5, underlie region-specific skeletal dysplasias, such as achondroplasia, campomelic dysplasia, and split-hand/foot malformation, demonstrating the lasting impacts of embryonic patterning errors. Based on these insights, regenerative strategies are increasingly drawing upon developmental principles, with organoid cultures recapitulating ossification centers, biomimetic hydrogels engineered for spatiotemporal morphogen delivery, and stem cell- or exosome-based therapies harnessing developmental microRNA networks. By bridging developmental biology with biomaterials science, these approaches provide both a roadmap to unravel skeletal disorders and a blueprint for next-generation therapies to reconstruct functional bones with the precision of the embryonic blueprint.
Role of SoxE transcription factors in development and disease.
Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders. SoxE proteins play critical roles during the development of multiple tissues in vertebrate embryos, including the neural crest, inner ear, cartilages, and glia cells of diverse origins, heart, gonads, and gastrointestinal tract. Because they recognize the same DNA sequence, possess conserved functional domains, and have overlapping expression profiles, SoxE proteins act partly redundantly in many contexts. However, Sox8, Sox9, and Sox10 also have many unique and tissue-specific functions. In particular, Sox9 plays an essential role in chondrogenesis, whereas Sox10 is a central regulator of pigment and glia cells. The highly context-specific regulation of different sets of target genes by SoxE factors is due to their ability to interact and cooperate with many other proteins including other transcription factors, cofactors, and enzymes, which modulate their regulatory activity. The activity of SoxE proteins is also frequently altered in a context-dependent fashion by post-translational modifications such as phosphorylation, acetylation, and SUMOylation.
A long-term survivor of campomelic dysplasia with 46,XY disorder of sex development and hypogonadotropic hypogonadism.
In this report, we present an adolescent patient with a 46,XY karyotype and phenotypically female genitalia secondary to campomelic dysplasia who presented with primary amenorrhea. This patient is unique both for her extended survival and presentation of hypogonadotropic hypogonadism, an unexpected finding in a disease characterised by gonadal dysgenesis that does not normally affect the central pituitary axis. Furthermore, while we might have expected elevated gonadotropins consistent with primary gonadal failure, this patient instead demonstrated low gonadotropin levels with minimally detectable sex steroids, reflecting central hypogonadism and complete functional gonadal failure. This patient was treated with a ¼ of a 0.025 mg estradiol patch (equating to a dose of 0.00625 mg) with plans to titrate to increased doses over the course of 1 year in order to induce puberty, promote bone growth and allow for gender identity concordance.
Upstream SOX9 deletion in a 46,XY girl with acampomelic campomelic dysplasia and absent minipuberty.
Campomelic dysplasia (CD) is a rare congenital skeletal dysplasia frequently associated with differences of sex development (DSD). In about 10% of affected individuals, the bowing of the long bones (campomelia) is absent, referred to as acampomelic campomelic dysplasia (ACD). Most patients with ACD carry heterozygous pathogenic variants within the SOX9 coding region or balanced chromosomal rearrangements involving the 17q24 region. A rarer mechanism involves deletions located upstream of the SOX9 gene. Only five ACD cases with upstream deletions of SOX9 have been reported in the medical literature. We report a female patient affected by ACD with Pierre Robin sequence, complete gonadal dysgenesis (CGD), and hypotonia. Genetic testing revealed a de novo 1.671 Mb deletion located 191 kb upstream of the SOX9 gene. This chromosomal aberration represents the second-largest deletion upstream of SOX9 reported to date. In addition, we describe the patient's endocrine profile, which revealed an absent gonadotropin rise during minipuberty, followed by a delayed increase in infancy. This study expands the clinical and molecular spectrum of ACD, enhancing our understanding of genotype-phenotype correlations of this condition. The phenotypic and endocrinological description of the proband may be helpful for clinicians who consult patients with DSD and skeletal dysplasia.
SOX9 haploinsufficiency reveals SOX9-Noggin interaction in BMP-SMAD signaling pathway in chondrogenesis.
Campomelic Dysplasia (CD) is a rare congenital disease caused by haploinsufficiency (HI) in SOX9. Patients with CD typically present with skeletal abnormalities and 75% of them have sex reversal. In this study, we use CRISPR/Cas9 to generate a human induced pluripotent stem cell (hiPSC) model from a heathy male donor, based on a previously reported SOX9 splice site mutation in a CD patients. This hiPSCs-derived chondrocytes from heterozygotes (HT) and homozygotes (HM) SOX9 mutation carriers showed significant defects in chondrogenesis. Bulk RNA profiling revealed that the BMP-SMAD signaling pathway, ribosome-related, and chromosome segregation-related gene sets were altered in the HT chondrocytes. The profile also showed significant noggin upregulation in CD chondrocytes, with ChIP-qPCR confirming that SOX9 binds to the distal regulatory element of noggin. This suggests SOX9 plays a feedback role in the BMP signaling pathway by modulating noggin expression rather than acting solely as a downstream regulator. This provides further insights into its dosage sensitivity in chondrogenesis. Overexpression of SOX9 showed promising results with improved sulfated glycosaminoglycans (GAGs) aggregation and COL2A1 expression following differentiation. We hope this finding could provide a better understanding of the dosage-dependent role of SOX9 in chondrogenesis and contribute to the development of improved therapeutic targets for CD patients.
