Genes affected

IL11 (HGNC:5966): (interleukin 11) The protein encoded by this gene is a member of the gp130 family of cytokines. These cytokines drive the assembly of multisubunit receptor complexes, all of which contain at least one molecule of the transmembrane signaling receptor IL6ST (gp130). This cytokine is shown to stimulate the T-cell-dependent development of immunoglobulin-producing B cells. It is also found to support the proliferation of hematopoietic stem cells and megakaryocyte progenitor cells. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jun 2012]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.003406167).

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0184 (2803/152200) while in subpopulation SAS AF = 0.0352 (170/4832). AF 95% confidence interval is 0.0309. There are 25 homozygotes in GnomAd4. There are 1365 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 25 AR gene
