Genes affected

SATB1 (HGNC:10541): (SATB homeobox 1) This gene encodes a matrix protein which binds nuclear matrix and scaffold-associating DNAs through a unique nuclear architecture. The protein recruits chromatin-remodeling factors in order to regulate chromatin structure and gene expression. [provided by RefSeq, Apr 2016]

SATB1 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 1 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), SATB1. . Gene score misZ 3.9832 (greater than the threshold 3.09). Trascript score misZ 4.7333 (greater than threshold 3.09). GenCC has associacion of gene with syndromic intellectual disability, developmental delay with dysmorphic facies and dental anomalies.
• BP4: Computational evidence support a benign effect (MetaRNN=0.12561518).
