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]

TBC1D5 (HGNC:19166): (TBC1 domain family member 5) Enables AP-2 adaptor complex binding activity and retromer complex binding activity. Involved in several processes, including macroautophagy; positive regulation of receptor internalization; and retrograde transport, endosome to Golgi. Located in Golgi apparatus; autophagosome; and endosome membrane. Part of retromer complex. Colocalizes with AP-2 adaptor complex and Atg1/ULK1 kinase complex.

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BS2: High AC in GnomAdExome4 at 6 AD gene.
