Special Issue Information

Dear Colleagues,

Achondroplasia (ACH), the most common form of short-limbed skeletal dysplasia, is caused by activating mutations in the fibroblast growth factor receptor 3 (FGFR3) gene. Patients with ACH suffer from various neurological, otolaryngologic and orthopaedic problems for a lifetime. Multidisciplinary medical approaches from early childhood are required to maintain a long-term patient’s quality of life. Several researches to develop therapeutic drugs have focused on target inhibition of the activated FGFR3 signaling in growth plate chondrocytes. Some of the drugs including BMN111, infigratinib, and TransCon CNP, are currently on-going clinical trials.  

In this special issue, we would like to review current therapeutic approaches for diverse disease-specific problems, including short stature, spinal canal stenosis, sleeping apnea, foramen magnum stenosis, and upper-airway obstruction. We will also discuss exciting advances of novel pharmacological development for future clinical applications and describe molecular mechanisms of these candidate drugs on the therapeutic potential.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Achondroplasia (ACH) is a disease caused by a missense mutation in the FGFR3 (fibroblast growth factor receptor 3) gene, which is the most common cause of short stature in humans. The treatment of ACH is necessary and urgent because untreated achondroplasia has many complications, both orthopedic and neurological, which ultimately lead to disability. This review presents the current and potential pharmacological treatments for achondroplasia, highlighting the advantages and disadvantages of all the drugs that have been demonstrated in human and animal studies in different stages of clinical trials. The article includes the potential impacts of drugs on achondroplasia symptoms other than short stature, including their effects on spinal canal stenosis, the narrowing of the foramen magnum and the proportionality of body structure. Addressing these effects could significantly improve the quality of life of patients, possibly reducing the frequency and necessity of hospitalization and painful surgical procedures, which are currently the only therapeutic options used. The criteria for a good drug for achondroplasia are best met by recombinant human growth hormone at present and will potentially be met by vosoritide in the future, while the rest of the drugs are in the early stages of clinical trials.
