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 GeneticsJun 11, 2021The c.2114C>A (p.A705D) alteration is located in exon 18 (coding exon 18) of the SMURF2 gene. This alteration results from a C to A substitution at nucleotide position 2114, causing the alanine (A) at amino acid position 705 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
