Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2024The c.3226G>T (p.A1076S) alteration is located in exon 11 (coding exon 11) of the RBM20 gene. This alteration results from a G to T substitution at nucleotide position 3226, causing the alanine (A) at amino acid position 1076 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
