Description

The c.905A>G (p.E302G) alteration is located in exon 2 (coding exon 2) of the KCNJ1 gene. This alteration results from an A to G substitution at nucleotide position 905, causing the glutamic acid (E) at amino acid position 302 to be replaced by a glycine (G). This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). This amino acid position is highly conserved in available vertebrate species. This alteration is predicted to be deleterious by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
