Test Overview
Test Methodology

The coding exons and associated, adjacent consensus splice sites of the MBD5 gene are amplified using specific primers, and bidirectionally sequenced using a fluorescent method.

Test Usage

Analysis for the presence of MBD5 (OMIM:611472) mutations in patients with a phenotype consistent with Mental Retardation Autosomal Dominant type 1 (OMIM:156200).

Reference Range *

Interpretive report provided.

Test Limitations

This assay will not detect large deletions in the MBD5 gene or intronic mutations outside the region sequenced in the MBD5 gene.
