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]

SATB2 Gene-Disease associations (from GenCC):

• chromosome 2q32-q33 deletion syndrome

  Inheritance: AD Classification: DEFINITIVE, STRONG, MODERATE Submitted by: Labcorp Genetics (formerly Invitae), G2P, Ambry Genetics
• SATB2 associated disorder

  Inheritance: AD Classification: DEFINITIVE Submitted by: Illumina, ClinGen

ACMG classification

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 2-199308804-C-T is Pathogenic according to our data. Variant chr2-199308804-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 422062.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP4: Computational evidence support a benign effect (MetaRNN=0.27782565). . Strength limited to SUPPORTING due to the PP5.

ClinVar contains an entry for this variant (Variation ID: 422062). For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects SATB2 function (PMID: 28151491). 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. This missense change has been observed in individual(s) with clinical features of SATB2-related conditions (PMID: 28151491). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 566 of the SATB2 protein (p.Glu566Lys).

Published functional studies suggest this variant impairs interaction with chromatin, however additional studies are needed to validate the functional effect of this variant in vivo (PMID: 28151491); In silico analysis suggests that this missense variant does not alter protein structure/function; Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 28151491, 33057194, 35982159, 35241104, denHoed2025[preprint])
