Genes affected

CYSLTR2 (HGNC:18274): (cysteinyl leukotriene receptor 2) The cysteinyl leukotrienes LTC4, LTD4, and LTE4 are important mediators of human bronchial asthma. Pharmacologic studies have determined that cysteinyl leukotrienes activate at least 2 receptors, the protein encoded by this gene and CYSLTR1. This encoded receptor is a member of the superfamily of G protein-coupled receptors. It seems to play a major role in endocrine and cardiovascular systems. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 21, 2023

The c.199T>C (p.Y67H) alteration is located in exon 1 (coding exon 1) of the CYSLTR2 gene. This alteration results from a T to C substitution at nucleotide position 199, causing the tyrosine (Y) at amino acid position 67 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
