Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the LRP1 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Endocytic receptor involved in endocytosis and in phagocytosis of apoptotic cells. Required for early embryonic development. Involved in cellular lipid homeostasis. Involved in the plasma clearance of chylomicron remnants and activated LRPAP1 (alpha 2-macroglobulin), as well as the local metabolism of complexes between plasminogen activators and their endogenous inhibitors. May modulate cellular events, such as APP metabolism, kinase-dependent intracellular signaling, neuronal calcium signaling as well as neurotransmission (PubMed:11907044, PubMed:12888553, PubMed:12713657). Acts as an alpha-2- macroglobulin receptor (PubMed:26142438). {ECO:0000269|PubMed:11907044, ECO:0000269|PubMed:12713657, ECO:0000269|PubMed:12888553, ECO:0000269|PubMed:26142438}.
• Disease: DISEASE: Keratosis pilaris atrophicans (KPA) [MIM:604093]: A group of rare genodermatoses characterized by keratotic follicular papules, variable degrees of inflammation, and secondary atrophic scarring. Most cases are associated with an atopic diathesis and keratosis pilaris on the extensor extremities. KPA is comprised of three distinct clinical subtypes: keratosis pilaris atrophicans faciei, atrophoderma vermiculatum, and keratosis follicularis spinulosa decalvans. Affected individuals may present with features overlapping the 3 subtypes. {ECO:0000269|PubMed:26142438}. Note=The disease is caused by mutations affecting the gene represented in this entry.
