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

ACMG classification

Our verdict: Benign. The variant received -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.79).
• BP7: Synonymous conserved (PhyloP=-1.24 with no splicing effect.
• BS1: Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.0000041 (6/1461782) while in subpopulation MID AF = 0.000347 (2/5768). AF 95% confidence interval is 0.0000609. There are 0 homozygotes in GnomAdExome4. There are 4 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAdExome4 at 6 AD gene.
