Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2 PP3

The NM_001366686.3(SIK3):​c.4055T>C​(p.Leu1352Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic 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. L1352R) has been classified as Uncertain significance.

The c.3737T>C (p.L1246P) alteration is located in exon 23 (coding exon 23) of the SIK3 gene. This alteration results from a T to C substitution at nucleotide position 3737, causing the leucine (L) at amino acid position 1246 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
