Cleidocranial dysplasia: case report of three siblings.

ABSTRACT: BACKGROUND:A family case report of cleidocranial dysplasia (CCD) with varied manifestations from father to three siblings is presented. CCD ( MIM # 119600) is a rare autosomal dominant skeletal dysplasia caused by CBAF1 gene ( OMIM 600211) with a wide range of variability. In all the cases generalized dysplasia in bone, prolonged retention of primary teeth and delayed eruption of permanent teeth were evident. Interestingly, there were no supernumerary teeth present. There was mandibular prognathism which was intercepted by occipital chin cup therapy. AIMS AND OBJECTIVE:To present the clinical manifestations, diagnostic imaging and treatment modalities along with dermatoglyphics in CCD patients. CONCLUSION:Cleidocranial dysplasia is an uncommon disorder however its clinical and radiological features are characteristic. In addition the CCD patients may be distinguished by specific dermatoglyphic markers. It carries with it several implications in terms of complications like skeletal malocclusion, dental caries, etc. Medical treatment is mainly directed at orthopedic and dental correction. A team approach to the management of dental abnormalities on a long-term basis with the overall goal to provide an esthetic facial appearance and functioning occlusion by late adolescence or early adulthood should be focused.

Project description:IntroductionMetaphyseal dysplasia describes a heterogenous group of skeletal dysplasias with varying inheritance patterns, which preferentially demonstrate dysplastic changes within the metaphyseal region of long bones. The clinical consequences of these dysplastic changes are highly variable, but most uniformly include decreased stature, increased upper-to-lower segment proportions, genu varus, and knee pain. Metaphyseal dysplasia, Spahr type (MDST) [MIM: 250400] is a rare primary bone dysplasia that was first clinically described in 1961 in four of five siblings with moderate short stature, metaphyseal dysplasia, mild genu vara, and no biochemical signs of rickets. For many decades, MDST was a clinical diagnosis, but the underlying genetic etiology was determined to be due to biallelic pathogenic variants in matrix metalloproteinases 13 [MIM: 600108] in 2014. Clinical case reports of this disease are limited; this paper aims to present the clinical manifestations and treatment for 3 Filipino siblings with a confirmed of MDST.Case reportPatient 1 presented at age 8 for medial ankle pain and bilateral lower extremity bowing of several years. Radiographs showed bilateral metaphyseal irregularities, and the patient underwent bilateral lateral distal femoral and proximal tibial physeal tethering at 9 years 11 months. At 16 months post tethering, she reports reduced pain although varus deformity persists. Patient 2 presented to clinic at age 6 for concern of bilateral bowing. He has had no reported pain and demonstrates milder metaphyseal irregularities than patient 1 on radiographs. To date, patient 2 has no significant changes or gross deformity. Patient 3 examined at 19 months without observable deformity.ConclusionSuspicion for MDST should be elevated in the setting of short-stature, upper-to-lower segment disproportionality, focal metaphyseal irregularities, and normal biochemical presentation. At present, no standard of care exists for treatment of patients with these deformities. Further, identification and evaluation of impacted patients are needed to progressively optimize management.
