Collection Method:clinical testing

The c.121C>G (p.R41G) alteration is located in exon 2 (coding exon 2) of the KIAA1217 gene. This alteration results from a C to G substitution at nucleotide position 121, causing the arginine (R) at amino acid position 41 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
