Adult onset neurodegenerative disorder v4.37 PSAP Sarah Leigh Tag Q2_23_promote_green was removed from gene: PSAP.
Adult onset neurodegenerative disorder v4.37 PSAP Sarah Leigh edited their review of gene: PSAP: Added comment: The rating of this gene has been updated to Green and the mode of inheritance set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted following NHS Genomic Medicine Service approval.; Changed mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Adult onset neurodegenerative disorder v4.36 PSAP Sarah Leigh Source NHS GMS was added to PSAP.
Source Expert Review Green was added to PSAP.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Adult onset neurodegenerative disorder v4.22 PSAP Sarah Leigh Tag Q2_23_promote_green tag was added to gene: PSAP.
Adult onset neurodegenerative disorder v4.22 PSAP Sarah Leigh edited their review of gene: PSAP: Added comment: Associated with Parkinson disease 24, autosomal dominant, susceptibility to (OMIM:619491), but not associated with the same condition in Gen2Phen. PMID: 32201884 reports three PSAP variants in three unrelated families with OMIM:619491. Supportive in vitro functional studies were also presented for the reported variants. However, it would appear that there maybe variable expressivity or incomplete penetrance of the Parkinson phenotype, as two variant carrying sibs in Family 2 had extrapyramidal signs, but did not have the full Parkinsons phenotype (PMID: 32201884).; Changed rating: GREEN
Adult onset neurodegenerative disorder v4.22 PSAP Sarah Leigh Classified gene: PSAP as Amber List (moderate evidence)
Adult onset neurodegenerative disorder v4.22 PSAP Sarah Leigh Added comment: Comment on list classification: There is enough evidence for this gene to be rated GREEN at the next major review.
Adult onset neurodegenerative disorder v4.22 PSAP Sarah Leigh Gene: psap has been classified as Amber List (Moderate Evidence).
Adult onset neurodegenerative disorder v4.21 PSAP Sarah Leigh Phenotypes for gene: PSAP were changed from Parkinson disease, AD to {Parkinson disease 24, autosomal dominant, susceptibility to}, OMIM:619491
Adult onset neurodegenerative disorder v2.42 PSAP Zornitza Stark gene: PSAP was added
gene: PSAP was added to Neurodegenerative disorders - adult onset. Sources: Literature
Mode of inheritance for gene: PSAP was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: PSAP were set to 32201884
Phenotypes for gene: PSAP were set to Parkinson disease, AD
Review for gene: PSAP was set to GREEN
Added comment: Well established gene-disease association for bi-allelic variants.

Now early-onset PD reported with mono-allelic variants. 6 affecteds from 3 families. Age of onset ranges from 33-60. Functional studies: Autophagic vacuole accumulation in skin fibroblasts , a-Synuclein aggregation and PSAP retention in the ER and abnormal intracellular accumulation in iPSC-dopaminergic neurons. Mouse model for one of 1 of the variants had motor deficits and dopaminergic neurodegeneration.
