Scientific background:

Summary: The protein is a component of a mutiprotein complex associated with chromatin. Mutations cause autosomal recessive Schimke immunoosseous dysplasia.

Methodology:

	research test	Method		Genomic sequencing of the entire coding region
		Turn-around time		5 working days
		Effort		5 working days
		Specimen		DNA
		Quality assessment		Internal quality control only
	All known and new missense, nonsense and splice mutations can be detected.
	research test	Method		Gene dosage measurements
		Turn-around time		25 working days
		Effort		25 working days
		Specimen		DNA
		Quality assessment		Internal quality control only
	Of the gene rearrangements, this method is useful to detect large deletions or duplications.
