Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_019590.5(KIAA1217):​c.187A>G​(p.Ile63Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I63N) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.187A>G (p.I63V) alteration is located in exon 2 (coding exon 2) of the KIAA1217 gene. This alteration results from a A to G substitution at nucleotide position 187, causing the isoleucine (I) at amino acid position 63 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
