Genes affected

TRABD2B (HGNC:44200): (TraB domain containing 2B) Enables Wnt-protein binding activity and metalloendopeptidase activity. Involved in several processes, including negative regulation of Wnt signaling pathway; positive regulation of protein oxidation; and positive regulation of protein-containing complex assembly. Is integral component of organelle membrane and integral component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Jan 18, 2022

The c.1012G>A (p.V338I) alteration is located in exon 5 (coding exon 5) of the TRABD2B gene. This alteration results from a G to A substitution at nucleotide position 1012, causing the valine (V) at amino acid position 338 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
