Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.806T>C (p.M269T) alteration is located in exon 2 (coding exon 1) of the KIAA1958 gene. This alteration results from a T to C substitution at nucleotide position 806, causing the methionine (M) at amino acid position 269 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
