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]

Ambry Genetics

Oct 20, 2023

The c.605C>T (p.P202L) alteration is located in exon 6 (coding exon 6) of the COL26A1 gene. This alteration results from a C to T substitution at nucleotide position 605, causing the proline (P) at amino acid position 202 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
