dbSNP rs982838565: BOK:p.Val179Asp (chr2-241572319-T-A) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3

The NM_032515.5(BOK):c.536T>A(p.Val179Asp) variant causes a missense change. The variant allele was found at a frequency of 0.00000411 in 1,459,296 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. V179A) has been classified as Uncertain significance.

Genes affected

BOK (HGNC:1087): (BCL2 family apoptosis regulator BOK) The protein encoded by this gene belongs to the BCL2 family, members of which form homo- or heterodimers, and act as anti- or proapoptotic regulators that are involved in a wide variety of cellular processes. Studies in rat show that this protein has restricted expression in reproductive tissues, interacts strongly with some antiapoptotic BCL2 proteins, not at all with proapoptotic BCL2 proteins, and induces apoptosis in transfected cells. Thus, this protein represents a proapoptotic member of the BCL2 family. [provided by RefSeq, Sep 2011]

Collection Method:clinical testing

The c.536T>A (p.V179D) alteration is located in exon 5 (coding exon 4) of the BOK gene. This alteration results from a T to A substitution at nucleotide position 536, causing the valine (V) at amino acid position 179 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
