Uncertain significance, criteria provided, single submitter	clinical testing	Fulgent Genetics, Fulgent Genetics	Jul 27, 2021	- -
Uncertain significance, criteria provided, single submitter	research	Petrovsky National Research Centre of Surgery, The Federal Agency for Scientific Organizations	Jul 04, 2018	The results of multiple bioinformatic predictions are controversial. However, p.S415N variant was detected in gene with pathogenic missenses common (PP2 criteria in ACMG Guidelines). It is also absent from population databases (PM2 criteria in ACMG Guidelines). In summary the p.S415N variant can be classified as variant with unknown clinical significance. The p.S415N variant discovered in female patient with early-onset dilatation cardiomyopathy (pediatric DCM) and heart failure. The patient underwent heart transplantation at the age of 19. -

Has not been previously published as pathogenic or benign to our knowledge; Reported in ClinVar as a variant of uncertain significance (ClinVar Variant ID# 548140; Landrum et al., 2016); In silico analysis supports that this missense variant does not alter protein structure/function -

The p.S415N variant (also known as c.1244G>A), located in coding exon 2 of the RBM20 gene, results from a G to A substitution at nucleotide position 1244. The serine at codon 415 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
