Test Overview
Test Methodology

The coding exons and associated, adjacent consensus splice sites of the MEF2C gene are amplified using specific primers, and bidirectionally sequenced using a fluorescent method.

Test Usage

Analysis for the presence of MEF2C mutations in patients with characteristics of mental retardation, autism, delayed motor development, epilepsy, with or without cerebral malformations.

Reference Range *

Interpretive report provided.

Test Limitations

This assay will not detect large deletions in the MEF2C gene or intronic mutations outside the region sequenced in the MEF2C gene.
