Genes affected

COL26A1 (HGNC:18038): (collagen type XXVI alpha 1 chain) This gene encodes a protein containing an emilin domain and two collagen stretches. This gene may be associated with aspirin-intolerant asthma. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2013]

Feb 27, 2024

The c.419G>A (p.R140Q) alteration is located in exon 4 (coding exon 4) of the COL26A1 gene. This alteration results from a G to A substitution at nucleotide position 419, causing the arginine (R) at amino acid position 140 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
