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]

The c.1991A>G (p.D664G) alteration is located in exon 17 (coding exon 17) of the SMURF2 gene. This alteration results from a A to G substitution at nucleotide position 1991, causing the aspartic acid (D) at amino acid position 664 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
