The c.488C>A (p.A163D) alteration is located in exon 4 (coding exon 2) of the NRSN1 gene. This alteration results from a C to A substitution at nucleotide position 488, causing the alanine (A) at amino acid position 163 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
