Variant 20-3671667-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_025220.5(ADAM33):c.1819C>T(p.Arg607Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000196 in 1,582,298 control chromosomes in the GnomAD database, including 1 homozygotes. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R607Q) has been classified as Uncertain significance.

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 13, 2022

The c.1819C>T (p.R607W) alteration is located in exon 16 (coding exon 16) of the ADAM33 gene. This alteration results from a C to T substitution at nucleotide position 1819, causing the arginine (R) at amino acid position 607 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
