Genes affected
SMURF2 (HGNC:16809): (SMAD specific E3 ubiquitin protein ligase 2) Enables SMAD binding activity; identical protein binding activity; and ubiquitin-protein transferase activity. Involved in negative regulation of transforming growth factor beta receptor signaling pathway; positive regulation of trophoblast cell migration; and ubiquitin-dependent SMAD protein catabolic process. Located in nuclear speck. Part of ubiquitin ligase complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 13, 2024The c.652G>A (p.A218T) alteration is located in exon 8 (coding exon 8) of the SMURF2 gene. This alteration results from a G to A substitution at nucleotide position 652, causing the alanine (A) at amino acid position 218 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
