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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0000986 (15/152128) while in subpopulation AFR AF = 0.000217 (9/41496). AF 95% confidence interval is 0.000113. There are 0 homozygotes in GnomAd4. There are 8 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.583C>T (p.R195W) alteration is located in exon 8 (coding exon 7) of the BCAS3 gene. This alteration results from a C to T substitution at nucleotide position 583, causing the arginine (R) at amino acid position 195 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
