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]

The c.284C>T (p.S95L) alteration is located in exon 2 (coding exon 2) of the TRABD2B gene. This alteration results from a C to T substitution at nucleotide position 284, causing the serine (S) at amino acid position 95 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
