dbSNP rs775970880: BCL11A:p.Pro730Ser (chr2-60460724-G-A) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 3P and 1B. PM2PP2BP4

The NM_022893.4(BCL11A):c.2188C>T(p.Pro730Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000186 in 1,614,014 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 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. P730T) has been classified as Uncertain significance.

Genes affected

BCL11A (HGNC:13221): (BCL11 transcription factor A) This gene encodes a C2H2 type zinc-finger protein by its similarity to the mouse Bcl11a/Evi9 protein. The corresponding mouse gene is a common site of retroviral integration in myeloid leukemia, and may function as a leukemia disease gene, in part, through its interaction with BCL6. During hematopoietic cell differentiation, this gene is down-regulated. It is possibly involved in lymphoma pathogenesis since translocations associated with B-cell malignancies also deregulates its expression. Multiple transcript variants encoding several different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the BCL11A gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 12 curated pathogenic missense variants (we use a threshold of 10). The gene has 12 curated benign missense variants. Gene score misZ: 3.835 (above the threshold of 3.09). Trascript score misZ: 3.6065 (above the threshold of 3.09). GenCC associations: The gene is linked to intellectual disability, autosomal dominant 40, Dias-Logan syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.3294574).
