Diagnostic, treatment and outcome possibilities in achondroplasia.


ABSTRACT:

Introduction

Achondroplasia is a common form of chondrodysplasia. It is transmitted by autosomal dominant trait. The disease is determined by mutations in receptor-3 gene of the fibroblast growth factor. The most frequent mutations are c.1138G>A and c.1183G>C; c.1138A. The diagnosis can usually be made on the basis of clinical characteristics and specific features on radiographs. It is not necessary to perform molecular testing in every child with a clinical diagnosis of achondroplasia.The aim of this study is to establish the diagnostic, treatment and outcome possibilities in patients with achondroplasia in our care.

Method

The study group consisted of 27 patients with achondroplasia. The method consisted of: clinical and radiological examinations. The DNA analasys was performed by PCR-RFLP technique.

Results

80 patients were diagnosed with bone dysplasia; 24 of them were diagnosed (on clinical and radiological basis) with achondroplasia. Out of this group, 16 patients were identified as heterozygotes for G1138A mutation in FGFR3 gene; 3 patients undergoing treatment with somatotropic hormone; the growth rate is improving from 0.1 cm/month to 0.5 cm/month.

Conclusions

In achondroplasia diagnosis is based on clinical and radiological criteria. It is the first study that reports the prevelance of this mutation in Romania.
