Genes affected

BCAS3 (HGNC:14347): (BCAS3 microtubule associated cell migration factor) Enables several functions, including acetyltransferase activator activity; beta-tubulin binding activity; and histone acetyltransferase binding activity. Involved in cellular response to estrogen stimulus; positive regulation of catalytic activity; and positive regulation of transcription by RNA polymerase II. Located in nucleus; phagophore assembly site; and transcriptionally active chromatin. Biomarker of breast cancer. [provided by Alliance of Genome Resources, Apr 2022]

TBX2-AS1 (HGNC:50355): (TBX2 antisense RNA 1)

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.10170427).
• BS1: Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000233 (34/1461638) while in subpopulation AMR AF = 0.00076 (34/44722). AF 95% confidence interval is 0.000559. There are 0 homozygotes in GnomAdExome4. There are 11 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
