Genetic Variant SIK3:p.Leu1352Arg (chr11-116846451-A-C) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3

The NM_001366686.3(SIK3):c.4055T>G(p.Leu1352Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000041 in 1,461,886 control chromosomes in the GnomAD database, including 1 homozygotes. 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. L1352P) has been classified as Uncertain significance.

The c.3737T>G (p.L1246R) alteration is located in exon 23 (coding exon 23) of the SIK3 gene. This alteration results from a T to G substitution at nucleotide position 3737, causing the leucine (L) at amino acid position 1246 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
