Genes affected

SATB2 (HGNC:21637): (SATB homeobox 2) This gene encodes a DNA binding protein that specifically binds nuclear matrix attachment regions. The encoded protein is involved in transcription regulation and chromatin remodeling. Defects in this gene are associated with isolated cleft palate and cognitive disability. Alternate splicing results in multiple transcript variants that encode the same protein. [provided by RefSeq, Feb 2010]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the SATB2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 38 curated pathogenic missense variants (we use a threshold of 10). The gene has 65 curated benign missense variants. Gene score misZ: 4.0511 (above the threshold of 3.09). Trascript score misZ: 5.5168 (above the threshold of 3.09). GenCC associations: The gene is linked to chromosome 2q32-q33 deletion syndrome, SATB2 associated disorder.

BP4

Computational evidence support a benign effect (MetaRNN=0.11773586).

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces alanine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 728 of the SATB2 protein (p.Ala728Gly). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SATB2-related conditions. ClinVar contains an entry for this variant (Variation ID: 654229). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) indicates that this missense variant is not expected to disrupt SATB2 function with a negative predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
