Genetic Variant BCAS3:p.Pro552Ser (chr17-61034682-C-T) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 4P and 6B. PM2PM5BP4_ModerateBS1

The NM_017679.5(BCAS3):c.1654C>T(p.Pro552Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000684 in 1,608,510 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P552L) has been classified as Likely pathogenic.

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 -2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr17-61034683-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 993270.Status of the report is no_assertion_criteria_provided, 0 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.11719784).

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.0000197 (3/152130) while in subpopulation EAS AF = 0.000385 (2/5198). AF 95% confidence interval is 0.0000681. There are 0 homozygotes in GnomAd4. There are 0 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
