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]

The c.106G>A (p.G36S) alteration is located in exon 1 (coding exon 1) of the COL26A1 gene. This alteration results from a G to A substitution at nucleotide position 106, causing the glycine (G) at amino acid position 36 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
