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-ÃŽÂºB signaling pathway. It is involved in the control of neuronal cell differentiation.
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, and select noncoding variants. Our assay provides a Q30 quality-adjusted mean coverage depth of 350x (50x minimum, or supplemented with additional analysis). Variants classified as pathogenic or likely pathogenic are confirmed with orthogonal methods, except individual variants that have high quality scores and previously validated in at least ten unrelated samples.
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.
