Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.590G>A (p.S197N) alteration is located in exon 6 (coding exon 6) of the KIAA0930 gene. This alteration results from a G to A substitution at nucleotide position 590, causing the serine (S) at amino acid position 197 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
