Genes affected

TRA2B (HGNC:10781): (transformer 2 beta homolog) This gene encodes a nuclear protein which functions as sequence-specific serine/arginine splicing factor which plays a role in mRNA processing, splicing patterns, and gene expression. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2011]

ACMG classification

Classification made for transcript

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), TRA2B. . Gene score misZ 3.4968 (greater than the threshold 3.09). Trascript score misZ 4.2084 (greater than threshold 3.09). GenCC has associacion of gene with complex neurodevelopmental disorder.

BP4

Computational evidence support a benign effect (MetaRNN=0.22938856).

The c.771T>G (p.D257E) alteration is located in exon 7 (coding exon 7) of the TRA2B gene. This alteration results from a T to G substitution at nucleotide position 771, causing the aspartic acid (D) at amino acid position 257 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
