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 18 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 2-199349006-G-A is Pathogenic according to our data. Variant chr2-199349006-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 373586.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr2-199349006-G-A is described in Lovd as [Pathogenic]. Variant chr2-199349006-G-A is described in Lovd as [Pathogenic].
