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

Classification was made for transcript

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

BP4
Computational evidence support a benign effect (MetaRNN=0.20894262).
BS1
Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000103 (15/1461074) while in subpopulation AMR AF = 0.000224 (10/44686). AF 95% confidence interval is 0.000121. There are 0 homozygotes in GnomAdExome4. There are 8 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

The c.2774C>T (p.T925I) alteration is located in exon 25 (coding exon 24) of the BCAS3 gene. This alteration results from a C to T substitution at nucleotide position 2774, causing the threonine (T) at amino acid position 925 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
