Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.869C>A (p.A290E) alteration is located in exon 6 (coding exon 6) of the KIAA1217 gene. This alteration results from a C to A substitution at nucleotide position 869, causing the alanine (A) at amino acid position 290 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
