The c.10558A>G (p.N3520D) alteration is located in exon 70 (coding exon 70) of the CSMD1 gene. This alteration results from a A to G substitution at nucleotide position 10558, causing the asparagine (N) at amino acid position 3520 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
