Genes affected
SYNJ1 (HGNC:11503): (synaptojanin 1) This gene encodes a phosphoinositide phosphatase that regulates levels of membrane phosphatidylinositol-4,5-bisphosphate. As such, expression of this enzyme may affect synaptic transmission and membrane trafficking. Multiple transcript variants encoding different isoforms have been found for this gene.

Early-onset Parkinson disease 20;C4479313:Developmental and epileptic encephalopathy, 53 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 23, 2022This sequence change replaces proline, which is neutral and non-polar, with glutamine, which is neutral and polar, at codon 1111 of the SYNJ1 protein (p.Pro1111Gln). This variant is present in population databases (rs771524798, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with SYNJ1-related conditions. ClinVar contains an entry for this variant (Variation ID: 565611). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
