The c.5525G>A (p.S1842N) alteration is located in exon 47 (coding exon 47) of the KIAA0368 gene. This alteration results from a G to A substitution at nucleotide position 5525, causing the serine (S) at amino acid position 1842 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
