Associated disorders

The PNPLA6 gene is associated with a spectrum of autosomal recessive neurological conditions, including hereditary spastic paraplegia 39 (SPG39) (MedGen UID: 383142), Boucher-Neuhauser syndrome (BNHS) (MedGen UID: 347798), Oliver-McFarlane syndrome (OMCS) (MedGen UID: 338532), and Lawrence-Moon syndrome (LNMS) (MedGen UID: 44078).

PNPLA6 is a rare cause of HSP, and the percentage of HSP attributed to pathogenic variants identified in PNPLA6 is unknown.

The PNPLA6 gene encodes the patatin-like phospholipase domain-containing protein 6. This protein metabolizes phosphatidylcholine into its constituent fatty acids and glycerophosphocholine, a precursor of the key neurotransmitter acetycholine, and is expressed in the central nervous system.

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.
