Description

The c.103G>A (p.G35S) alteration is located in exon 2 (coding exon 1) of the SCN5A gene. This alteration results from a G to A substitution at nucleotide position 103, causing the glycine (G) at amino acid position 35 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
