Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP3BP6
The NM_003036.4(SKI):c.191_196dup(p.Val64_Pro65dup) variant causes a inframe insertion change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000999 in 1,401,326 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. P63P) has been classified as Likely benign.

Shprintzen-Goldberg syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 11, 2016 | This sequence change inserts 6 nucleotides in exon 1 of the SKI mRNA (c.191_196dupTGCCCG). This leads to the insertion of 2 amino acid residues in the SKI protein (p.Val64_Pro65dup) but otherwise preserves the integrity of the reading frame. While this variant is not present in population databases (ExAC no frequency), the frequency information is unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has not been reported in the literature in an individual with a SKI-related disease. In summary, this variant is a novel in-frame duplication with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. - |
