dbSNP rs200061290: BCAS3:p.Pro909Gln (chr17-61392109-C-A) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_017679.5(BCAS3):c.2726C>A(p.Pro909Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,146 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P909R) has been classified as Uncertain significance.

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]
