PLEKHG5

Alias

CMTRIC; DSMA4; GEF720; Syx; Tech

Associated disorders

The PLEKHG5 gene is associated with autosomal recessive intermediate Charcot-Marie-Tooth disease type C (CMTRIC) (MedGen UID: 815639) and distal hereditary motor neuropathy, also known as distal spinal muscular atrophy 4 (DSMA4) (MedGen UID: 369682).

Pathogenic variants in PLEKHG5 cause an unknown percentage of CMT and distal spinal muscular atrophy.

The PLEKHG5 gene encodes the pleckstrin homology domain-containing protein G5. This protein is predominantly expressed in the peripheral nervous system and is suggested to have a role in the activation of the RhoA exchange factor and NF-κB signaling pathway. It is involved in the control of neuronal cell differentiation.

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.
