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

Verdict is Pathogenic. Variant got 12 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), SATB2. . Gene score misZ 4.0511 (greater than the threshold 3.09). Trascript score misZ 5.5168 (greater than threshold 3.09). GenCC has associacion of gene with chromosome 2q32-q33 deletion syndrome, SATB2 associated disorder.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.834
• PP5: Variant 2-199272449-G-A is Pathogenic according to our data. Variant chr2-199272449-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 436636.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr2-199272449-G-A is described in Lovd as [Likely_pathogenic].
