Special Issue Information

Dear Colleagues, 

Primary Ciliary Dyskinesia (PCD) is a rare respiratory disease characterized by an alteration in ciliary function, patients exhibiting classic symptoms such as neonatal respiratory distress, recurrent airway infections, chronic rhinitis, otitis media and sinusitis, laterality defects, and male infertility. Diagnosis is complex with no currently existing gold standard technique. Studying ciliary function and structure combined with genetics and compatible clinical symptoms are all required in order to arrive to a conclusive diagnosis. The management of PCD patients is very challenging, and an early diagnosis is vital in order for a better prognosis.

In this Special Issue, we look for original papers and reviews based on the early and accurate diagnosis, treatment guidelines, and experimental gene therapy in PCD, including, but not limited to, the following topics: (i) advances in PCD diagnostic techniques, including high-speed video microscopy, electron microscopy, immunofluorescence analysis, and potential serological determinations; (ii) new methods and analysis models for the objective determination of the ciliary beat that allows a rapid diagnosis of the disease;  (iii) advances in genetics of PCD, including new mutations and correlations regarding the genotype–phenotype of this rare disease;  (iv) airway epithelial cell culture advances;  (v) progress in the management of adult and children PCD patients according to their diagnosis; (vi) new therapeutic approaches for PCD patients; (vii) gene therapy in PCD.

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. Diagnostics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). 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.

Abstract
Primary ciliary dyskinesia (PCD) has been linked to more than 50 genes that cause a spectrum of clinical symptoms, including newborn respiratory distress, sinopulmonary infections, and laterality abnormalities.

Primary ciliary dyskinesia (PCD) has been linked to more than 50 genes that cause a spectrum of clinical symptoms, including newborn respiratory distress, sinopulmonary infections, and laterality abnormalities. Although the RSPH4A (c.921+3_6delAAGT) pathogenic variant has been related to Hispanic groups with Puerto Rican ancestry, it is uncertain how frequently other PCD-implicated genes are present on the island. A retrospective chart review of n = 127 genetic reports from Puerto Rican subjects who underwent genetic screening for PCD variants was conducted from 2018 to 2022. Of 127 subjects, 29.1% subjects presented PCD pathogenic variants, and 13.4% were homozygous for the RSPH4A (c.921+3_6delAAGT) founder mutation. The most common pathogenic variants were in RSPH4A and ZMYND10 genes. A description of the frequency and geographic distribution of implicated PCD pathogenic variants in Puerto Rico is presented. Our findings reconfirm that the presence of PCD in Puerto Rico is predominantly due to a founder pathogenic variant in the RSPH4A (c.921+3_6delAAGT) splice site. Understanding the frequency of PCD genetic variants in Puerto Rico is essential to map a future genotype-phenotype PCD spectrum in Puerto Rican Hispanics with a heterogeneous ancestry. Full article
