Genes affected

SIK3 (HGNC:29165): (SIK family kinase 3) Enables ATP binding activity; magnesium ion binding activity; and protein serine/threonine kinase activity. Involved in positive regulation of TORC1 signaling; positive regulation of TORC2 signaling; and protein phosphorylation. Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

APOA1-AS (HGNC:40079): (APOA1 antisense RNA)

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SIK3. . Trascript score misZ 3.9277 (greater than threshold 3.09). GenCC has associacion of gene with spondyloepimetaphyseal dysplasia, Krakow type.

The c.3530G>C (p.S1177T) alteration is located in exon 22 (coding exon 22) of the SIK3 gene. This alteration results from a G to C substitution at nucleotide position 3530, causing the serine (S) at amino acid position 1177 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
