Genes affected

TBL1XR1 (HGNC:29529): (TBL1X/Y related 1) This gene is a member of the WD40 repeat-containing gene family and shares sequence similarity with transducin (beta)-like 1X-linked (TBL1X). The protein encoded by this gene is thought to be a component of both nuclear receptor corepressor (N-CoR) and histone deacetylase 3 (HDAC 3) complexes, and is required for transcriptional activation by a variety of transcription factors. Mutations in these gene have been associated with some autism spectrum disorders, and one finding suggests that haploinsufficiency of this gene may be a cause of intellectual disability with dysmorphism. Mutations in this gene as well as recurrent translocations involving this gene have also been observed in some tumors. [provided by RefSeq, Mar 2016]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

PP2

Missense variant in the TBL1XR1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 50 curated pathogenic missense variants (we use a threshold of 10). The gene has 2 curated benign missense variants. Gene score misZ: 4.2042 (above the threshold of 3.09). Trascript score misZ: 5.2877 (above the threshold of 3.09). GenCC associations: The gene is linked to complex neurodevelopmental disorder, intellectual disability, autosomal dominant 41, Pierpont syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.13883331).

BS2

High AC in GnomAdExome4 at 7 AD gene.
