Variant summary

Our verdict is Pathogenic. Variant got 17 ACMG points: 17P and 0B. PM2PM5PP2PP3_StrongPP5_Very_Strong

The NM_024665.7(TBL1XR1):​c.1108G>A​(p.Asp370Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D370Y) has been classified as Pathogenic.

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 Pathogenic. Variant got 17 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr3-177038112-C-A is described in Lovd as [Pathogenic].
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 Pierpont syndrome, complex neurodevelopmental disorder, intellectual disability, autosomal dominant 41.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.957
PP5
Variant 3-177038112-C-T is Pathogenic according to our data. Variant chr3-177038112-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 372701.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
