UCD DNA Diagnostic Laboratory
DNA Analysis for Achondroplasia, Hypochondroplasia,
and Nonsyndromic Craniosynostosis
(Fibroblast Growth Factor 3 Receptor (FGFR3) Mutations)

General Information: We test for 99% of the mutations associated with achondroplasia (G380R), 60-90% of mutations associated with hypochondroplasia (N540K and K650M), and approximately 99% of mutations associated with nonsyndromic coronal craniosynostosis (P248C).

Methodology: PCR based direct mutation analysis for FGFR3 mutations are performed pursuant to a license agreement with Roche Molecular Systems, Inc.

Use: Prenatal diagnosis and identification of mutations in individuals with a clinical diagnosis of achondroplasia, hypochondroplasia

Indications: Confirmation of diagnosis where suspected on basis of clinical findings. Achondroplasia: Large head; bulging forehead; large calvarium; short, cupped ribs and rhizomelic shortening.
Hypochondroplasia: Rhizomelic shortening, normal head to slight prominence of forehead. Nonsyndromic coronal craniosynotosis.

Specimen Requirements: Please see Instructions for Shipping and Handling of Specimens.

Turnaround Time: 2-4 weeks (time required for culture of tissue specimens not included.) Cases are prioritized on an individual basis.
