[[http://www.uniprot.org/uniprot/NICA_HUMAN NICA_HUMAN]] Hidradenitis suppurativa. The disease is caused by mutations affecting the gene represented in this entry. [[http://www.uniprot.org/uniprot/PSN1_HUMAN PSN1_HUMAN]] Defects in PSEN1 are a cause of Alzheimer disease type 3 (AD3) [MIM:[http://omim.org/entry/607822 607822]]. AD3 is a familial early-onset form of Alzheimer disease. Alzheimer disease is a neurodegenerative disorder characterized by progressive dementia, loss of cognitive abilities, and deposition of fibrillar amyloid proteins as intraneuronal neurofibrillary tangles, extracellular amyloid plaques and vascular amyloid deposits. The major constituent of these plaques is the neurotoxic amyloid-beta-APP 40-42 peptide (s), derived proteolytically from the transmembrane precursor protein APP by sequential secretase processing. The cytotoxic C-terminal fragments (CTFs) and the caspase-cleaved products such as C31 derived from APP, are also implicated in neuronal death.<ref>PMID:12058025</ref> <ref>PMID:7596406</ref> <ref>PMID:8634711</ref> <ref>PMID:8634712</ref> <ref>PMID:7651536</ref> <ref>PMID:7550356</ref> <ref>PMID:8733303</ref> <ref>PMID:9225696</ref> <ref>PMID:9298817</ref> <ref>PMID:9172170</ref> <ref>PMID:9833068</ref> <ref>PMID:9384602</ref> <ref>PMID:9521423</ref> <ref>PMID:10200054</ref> <ref>PMID:9719376</ref> <ref>PMID:9507958</ref> <ref>PMID:9831473</ref> <ref>PMID:10441572</ref> <ref>PMID:10090481</ref> <ref>PMID:10447269</ref> <ref>PMID:10533070</ref> <ref>PMID:10025789</ref> <ref>PMID:10208579</ref> <ref>PMID:10439444</ref> <ref>PMID:10631141</ref> <ref>PMID:10644793</ref> <ref>PMID:11027672</ref> [:]<ref>PMID:11710891</ref> <ref>PMID:11920851</ref> <ref>PMID:12048239</ref> <ref>PMID:12484344</ref> <ref>PMID:12493737</ref>  Defects in PSEN1 are a cause of frontotemporal dementia (FTD) [MIM:[http://omim.org/entry/600274 600274]].  Defects in PSEN1 are the cause of cardiomyopathy dilated type 1U (CMD1U) [MIM:[http://omim.org/entry/613694 613694]]. It is a disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death.<ref>PMID:17186461</ref>  Defects in PSEN1 are the cause of familial acne inversa type 3 (ACNINV3) [MIM:[http://omim.org/entry/613737 613737]]. A chronic relapsing inflammatory disease of the hair follicles characterized by recurrent draining sinuses, painful skin abscesses, and disfiguring scars. Manifestations typically appear after puberty.<ref>PMID:20929727</ref>

[[http://www.uniprot.org/uniprot/PEN2_HUMAN PEN2_HUMAN]] Essential subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (beta-amyloid precursor protein). Probably represents the last step of maturation of gamma-secretase, facilitating endoproteolysis of presenilin and conferring gamma-secretase activity.<ref>PMID:12522139</ref> <ref>PMID:12763021</ref>  [[http://www.uniprot.org/uniprot/NICA_HUMAN NICA_HUMAN]] Essential subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (beta-amyloid precursor protein). It probably represents a stabilizing cofactor required for the assembly of the gamma-secretase complex. [[http://www.uniprot.org/uniprot/APH1A_HUMAN APH1A_HUMAN]] Essential subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral proteins such as Notch receptors and APP (beta-amyloid precursor protein). It probably represents a stabilizing cofactor for the presenilin homodimer that promotes the formation of a stable complex.<ref>PMID:12297508</ref> <ref>PMID:12522139</ref> <ref>PMID:12763021</ref> [[http://www.uniprot.org/uniprot/PSN1_HUMAN PSN1_HUMAN]] Probable catalytic subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (beta-amyloid precursor protein). Requires the other members of the gamma-secretase complex to have a protease activity. May play a role in intracellular signaling and gene expression or in linking chromatin to the nuclear membrane. Stimulates cell-cell adhesion though its association with the E-cadherin/catenin complex. Under conditions of apoptosis or calcium influx, cleaves E-cadherin promoting the disassembly of the E-cadherin/catenin complex and increasing the pool of cytoplasmic beta-catenin, thus negatively regulating Wnt signaling. May also play a role in hematopoiesis.<ref>PMID:10545183</ref> <ref>PMID:10593990</ref> <ref>PMID:10206644</ref> <ref>PMID:10899933</ref> <ref>PMID:10811883</ref> <ref>PMID:11226248</ref> <ref>PMID:15341515</ref> <ref>PMID:16305624</ref>
