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 made for transcript
Verdict is Likely_pathogenic. Variant got 6 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), TBL1XR1. . Gene score misZ: 4.2042 (greater than the threshold 3.09). Trascript score misZ: 5.2877 (greater than threshold 3.09). The gene has 50 curated pathogenic missense variants (we use a threshold of 10). The gene has 2 curated benign missense variants. GenCC has associacion of the gene with Pierpont syndrome, complex neurodevelopmental disorder, intellectual disability, autosomal dominant 41.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.897
PP5
Variant 3-177050010-G-A is Pathogenic according to our data. Variant chr3-177050010-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 521029.We mark this variant Likely_pathogenic, oryginal submissions are: {Uncertain_significance=1, Pathogenic=1, Likely_pathogenic=1}.
