The c.1811A>G (p.N604S) alteration is located in exon 5 (coding exon 4) of the LRRN4 gene. This alteration results from a A to G substitution at nucleotide position 1811, causing the asparagine (N) at amino acid position 604 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
