The c.488G>A (p.S163N) alteration is located in exon 3 (coding exon 3) of the LRRC73 gene. This alteration results from a G to A substitution at nucleotide position 488, causing the serine (S) at amino acid position 163 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
