CIZ1

Alias

LSFR1; NP94; ZNF356

Associated disorders

The CIZ1 gene currently has no well-established disease association; however, there is preliminary evidence supporting a correlation with autosomal dominant dystonia 23 (PMID: 22447717).

Invitae tests that include this gene:

CIZ1 is a rare cause of dystonia, and the percentage of dystonia attributed to pathogenic variants identified in CIZ1 is unknown.

CIZ1 encodes CIP1-interacting zinc finger protein. CIZ1 is expressed in the brain and has a role in DNA synthesis and cell-cycle control.

Assay and technical information

Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).

Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.

Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
