Genes affected
PSENEN (HGNC:30100): (presenilin enhancer, gamma-secretase subunit) Presenilins, which are components of the gamma-secretase protein complex, are required for intramembranous processing of some type I transmembrane proteins, such as the Notch proteins and the beta-amyloid precursor protein. Signaling by Notch receptors mediates a wide range of developmental cell fates. Processing of the beta-amyloid precursor protein generates neurotoxic amyloid beta peptides, the major component of senile plaques associated with Alzheimer's disease. This gene encodes a protein that is required for Notch pathway signaling, and for the activity and accumulation of gamma-secretase. Mutations resulting in haploinsufficiency for this gene cause familial acne inversa-2 (ACNINV2). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

This sequence change falls in intron 2 of the PSENEN gene. It does not directly change the encoded amino acid sequence of the PSENEN protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs201605573, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with PSENEN-related conditions. ClinVar contains an entry for this variant (Variation ID: 1493528). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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. -
