Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the LOXL3 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000032603.5. Only rare variants are included in the table.

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: Protein-lysine 6-oxidase that mediates the oxidation of peptidyl lysine residues to allysine in target proteins (PubMed:17018530, PubMed:28065600). Catalyzes the post- translational oxidative deamination of peptidyl lysine residues in precursors of elastin and different types of collagens, a prerequisite in the formation of cross-links between collagens and elastin (PubMed:17018530). Required for somite boundary formation by catalyzing oxidation of fibronectin (FN1), enhancing integrin signaling in myofibers and their adhesion to the myotendinous junction (MTJ) (By similarity). Acts as a regulator of inflammatory response by inhibiting differentiation of naive CD4(+) T-cells into T-helper Th17 or regulatory T-cells (Treg): acts by interacting with STAT3 in the nucleus and catalyzing both deacetylation and oxidation of lysine residues on STAT3, leading to disrupt STAT3 dimerization and inhibit STAT3 transcription activity (PubMed:28065600). Oxidation of lysine residues to allysine on STAT3 preferentially takes place on lysine residues that are acetylated (PubMed:28065600). Also able to catalyze deacetylation of lysine residues on STAT3 (PubMed:28065600). {ECO:0000250|UniProtKB:Q9Z175, ECO:0000269|PubMed:17018530, ECO:0000269|PubMed:28065600}.; FUNCTION: Isoform 2: Shows protein-lysine 6-oxidase activity toward elastin and different types of collagens, with the highest activity toward collagen type IV (PubMed:17018530). {ECO:0000269|PubMed:17018530}.;
Disease: DISEASE: Note=Defects in LOXL3 are found in a family with an autosomal recessive form of Stickler syndrome, an inherited disorder that associates ocular signs with more or less complete forms of Pierre Robin sequence and sensorineural deafness (PubMed:25663169). Pierre Robin sequence includes an opening in the roof of the mouth (a cleft palate) (PubMed:25663169). The degree of hearing loss varies among affected individuals and may become more severe over time (PubMed:25663169). Syndrome expressivity is variable (PubMed:25663169). Ocular disorders include non-progressive myopia with associated chorioretinal degeneration (PubMed:25663169). Defects in LOXL3 are found in another family with early-onset high myopia (PubMed:26957899). The disease may be caused by mutations affecting the gene represented in this entry (PubMed:25663169, PubMed:26957899). {ECO:0000269|PubMed:25663169, ECO:0000269|PubMed:26957899}.;
