MLL2 sequencing

MLL2 sequencing

Patients with Kabuki syndrome, also called Kabuki make-up syndrome (KMS) have characteristic facial features, short stature, congenital heart defects, skeletal anomalies, immunological abnormalities, and mild to moderate mental retardation.  Facial features include long palpebral fissures with eversion of the lower lateral eyelid, sparse and arched eyebrows, depressed nasal tip, and large prominent earlobes.  Other features include joint laxity, dental abnormalities, finger-tip pads, and renal/urinary tract anomalies. 

Mutations of the MLL2 (mixed lineage leukemia 2) gene were reported in 35/53 (66%) patients with KMS.  MLL2 encodes a Trithorax-group histone methyltransferase that belongs to the SET family.  We offer full gene sequencing of all 54 coding exons and intron/exon boundaries of MLL2 by direct sequencing of amplification products in both the forward and reverse directions.
