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 Benign. Variant got -8 ACMG points.

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=0.039176136).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000328 (5/152354) while in subpopulation AFR AF= 0.00012 (5/41592). AF 95% confidence interval is 0.0000472. There are 0 homozygotes in gnomad4. There are 4 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 5 AD gene.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

ClinVar contains an entry for this variant (Variation ID: 1023416). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SATB2 protein function. 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. This variant has not been reported in the literature in individuals affected with SATB2-related conditions. This sequence change replaces alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 728 of the SATB2 protein (p.Ala728Pro). This variant is present in population databases (rs377368865, gnomAD 0.02%). -
