Calcium-independent phospholipase involved in phospholipid remodeling with implications in cellular membrane homeostasis, mitochondrial integrity and signal transduction. Hydrolyzes the ester bond of the fatty acyl group attached at sn-1 or sn-2 position of phospholipids (phospholipase A1 and A2 activity respectively), producing lysophospholipids that are used in deacylation-reacylation cycles (PubMed:10092647, PubMed:10336645, PubMed:20886109, PubMed:9417066).

Neurodegeneration with brain iron accumulation 2B
A neurodegenerative disorder associated with iron accumulation in the brain, primarily in the basal ganglia. It is characterized by progressive extrapyramidal dysfunction leading to rigidity, dystonia, dysarthria and sensorimotor impairment.

Prospective 5-year natural history study of infantile PLA2G6-associated neurodegeneration.
To prospectively characterize the age of developmental milestone attainment and loss, disease milestone acquisition, and associations between a quality of life measure and age in 40 children with infantile PLA2G6-associated neurodegeneration (PLAN). We analysed developmental and disease milestones and health-related quality of life scores from the 97-item Infant Toddler Quality of Life Questionnaire (ITQOL-97) in a prospective, observational, longitudinal natural history study. Developmental and disease milestone attainments were visualized as histograms and Kaplan-Meier curves respectively. We used mixed-effects linear regression to assess the associations between ITQOL-97 domains and age and to compare marginal predictions to a US reference population. The study group was comprised of 19 males and 21 females with a mean age at enrollment of 5 years 1 month (SD 3 years; range 1 year 7 months-16 years 8 months). Over the course of the disease, children continued to vocalize, smile, and laugh, while other milestones like walking were rarely met at any time. ITQOL-97 domains differed significantly from a US reference population in all areas except for 'general behavior'. The 'physical abilities' domain had the greatest change with age (-6.24 per year). In this first prospective natural history study of infantile PLAN, we characterize developmental and disease milestones, and longitudinal associations, with quality of life metrics. These data will provide valuable disease norms for use as clinical references and in the design of interventional trials.

Adult-Onset PLA2G6-Associated Parkinsonism With Claval Hypertrophy: A Rare Radiological-Genetic Association.
A man in his 20s presented with rapidly progressive spastic parkinsonism, right-hand focal dystonia, memory impairment, and behavioural changes over eight months, resulting in complete dependence. Examination showed spasticity, rigidity, bradykinesia, ankle clonus, postural instability, slowed saccades, and cognitive deficits (Mini-Mental State Examination 25/30, Montreal Cognitive Assessment 20/30). Brain magnetic resonance imaging revealed mild cerebellar atrophy, claval hypertrophy, and minimal lentiform susceptibility blooming. Whole-exome sequencing identified a heterozygous pathogenic PLA2G6 variant (c.2222G>A; p.Arg741Gln). No family history was present. Symptomatic treatment with levodopa/carbidopa, trihexyphenidyl, and baclofen yielded partial initial benefit but limited sustained response over six months of follow-up. This case expands the adult-onset PLA2G6-associated neurodegeneration phenotype by combining aggressive progression, early cognitive involvement, and rare infantile-like neuroimaging features with minimal iron deposition.
