Genes affected

ADAM33 (HGNC:15478): (ADAM metallopeptidase domain 33) This gene encodes a member of the ADAM (a disintegrin and metalloprotease domain) family. Members of this family are membrane-anchored proteins structurally related to snake venom disintegrins, and have been implicated in a variety of biological processes involving cell-cell and cell-matrix interactions, including fertilization, muscle development, and neurogenesis. This protein is a type I transmembrane protein implicated in asthma and bronchial hyperresponsiveness. Alternative splicing results in multiple transcript variants encoding different isoforms.

Ambry Genetics

Dec 01, 2022

The c.2177G>A (p.R726Q) alteration is located in exon 19 (coding exon 19) of the ADAM33 gene. This alteration results from a G to A substitution at nucleotide position 2177, causing the arginine (R) at amino acid position 726 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
