Somatic development in cleidocranial dysplasia
1Royal Dental College, Copenhagen, Denmark.
Insights
Cleidocranial dysplasia (CCD) causes generalized skeletal dysplasia, affecting height and bone growth, particularly in females. This study reveals significant growth retardation and skeletal maturity delays in CCD patients.
Area of Science:
- Genetics and Developmental Biology
- Orthopedics
- Pediatric Endocrinology
Background:
- Cleidocranial dysplasia (CCD) is a rare genetic disorder affecting bone development.
- Previous research has focused on craniofacial anomalies, but general somatic development requires further investigation.
Purpose of the Study:
- To describe general somatic development in patients with cleidocranial dysplasia (CCD).
- To analyze the longitudinal growth patterns of individuals diagnosed with CCD.
Main Methods:
- Study included 17 patients (7 males, 10 females, aged 5-46 years) with CCD.
- Data collection involved family history, anthropometric measurements, and hand/forearm radiographs.
- Longitudinal growth was assessed in 11 patients over time.
Main Results:
- Significant decreases in height and radius length were observed, more pronounced in females.
- Longitudinal data indicated growth retardation and delayed skeletal maturity during childhood.
- Metacarpophalangeal pattern profile analysis revealed significant variation in bone lengths due to anomalies like extra epiphyses.
Conclusions:
- Cleidocranial dysplasia (CCD) is characterized by generalized skeletal dysplasia, impacting overall growth.
- The findings highlight the systemic nature of CCD beyond craniofacial manifestations.
- This study provides valuable insights into the growth patterns and skeletal anomalies in CCD patients.
Abstract:
As part of a more comprehensive investigation of general and craniofacial development in cleidocranial dysplasia (CCD), the present study describes general somatic development and analyzes longitudinal growth of 17 patients (seven males, ten females, aged 5-46 years) with CCD. Eleven were followed longitudinally. Data included family history, anthropometric measurements, and radiographs of the right hand and forearm. Height and radius length were significantly decreased, being most pronounced in females. The longitudinal growth data showed growth retardation and slightly retarded skeletal maturity throughout childhood. Metacarpophalangeal pattern profile analysis demonstrated great variation in bone lengths, presumably resulting from extra epiphyses in the 2nd and 5th metacarpals and from multiple cone-shaped epiphyses. Findings of the present study support the view that CCD is a generalized skeletal dysplasia.
