Genes affected

TUB (HGNC:12406): (TUB bipartite transcription factor) This gene encodes a member of the Tubby family of bipartite transcription factors. The encoded protein may play a role in obesity and sensorineural degradation. The crystal structure has been determined for a similar protein in mouse, and it functions as a membrane-bound transcription regulator that translocates to the nucleus in response to phosphoinositide hydrolysis. Two transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.77).

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000657 (100/152266) while in subpopulation NFE AF= 0.00113 (77/68010). AF 95% confidence interval is 0.000928. There are 0 homozygotes in gnomad4. There are 57 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
