Chondrodysplasia punctata, a skeletal dysplasia with craniofacial dysmorphism and joint contractures can occur with rhizomelia, mesomelia or both. The rhizomelic form is generally lethal, whereas one form of mesomelic chondrodysplasia punctata has been described that is associated with a presumably normal lifespan and intelligence. We describe a case of a fetus suspected prenatally of having rhizomelic chondrodysplasia punctata, who was subsequently diagnosed at 1.5 years of age to have the tibia-metacarpal form of chondrodysplasia punctata. The prenatal sonographic findings of second-trimester micromelic bone shortening and third-trimester proximal femoral stippling may be present in the rhizomelic form but are not specific to this condition.

Chondrodysplasia punctata (CP) is a rare skeletal dysplasia characterized by punctate calcifications in areas of endochondral ossification, with Conradi-Hünermann-Happle syndrome (CDPX2) being the most common form. This study presents a clinical case of a 10-month-old female child, diagnosed with CDPX2 following a referral from a neonatology department of a secondary hospital center to a genetics consultation at a tertiary hospital center in Portugal. Despite normal prenatal monitoring, postnatal evaluations revealed typical manifestations of the syndrome, including nasomaxillary hypoplasia, macrocephaly, and skeletal abnormalities confirmed through imaging.

Background: X-linked recessive chondrodysplasia punctata 1 (CDPX1) is a rare congenital skeletal dysplasia characterized by stippled epiphyses, nasal hypoplasia, and brachytelephalangy. ARSL (formerly known as ARSE), a member of the sulfatase gene family located on Xp22.3, has been identified as the causative gene for CDPX1.

Article Synopsis
  • This study analyzed pediatric patients with skeletal dysplasia to understand which subgroups frequently require operative airway evaluations and tracheostomies due to respiratory failure caused by airway issues.
  • Out of 313 initial patients, 41 met the criteria; 19 of these had tracheostomies, with specific diagnoses such as Filamins disorders and Chondrodysplasia punctata being more common among those requiring the intervention.
  • Findings emphasized that respiratory complications are common in skeletal dysplasia, with a significant number of patients undergoing tracheostomy, though only a few were successfully decannulated by the end of the study.

Article Synopsis
  • Peroxisome biogenesis disorders (PBDs) include various diseases with diverse symptoms like developmental delays, hearing loss, and liver issues, linked to genetic mutations affecting peroxisome function.* -
  • A patient was studied using whole-exome sequencing to identify genetic causes behind their clinical symptoms, which included developmental delays and organ enlargement, but no single-nucleotide mutations were found.* -
  • However, a homozygous deletion in exon 4 of the gene was identified, affecting the protein's transmembrane domain, which is crucial for normal cellular processes and peroxisome function.*
