Genes affected

THBS4-AS1 (HGNC:40583): (THBS4 antisense RNA 1)

THBS4-AS1 links:

THBS4 (HGNC:11788): (thrombospondin 4) The protein encoded by this gene belongs to the thrombospondin protein family. Thrombospondin family members are adhesive glycoproteins that mediate cell-to-cell and cell-to-matrix interactions. This protein forms a pentamer and can bind to heparin and calcium. It is involved in local signaling in the developing and adult nervous system, and it contributes to spinal sensitization and neuropathic pain states. This gene is activated during the stromal response to invasive breast cancer. It may also play a role in inflammatory responses in Alzheimer's disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.88).

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0215 (3281/152320) while in subpopulation SAS AF = 0.0319 (154/4826). AF 95% confidence interval is 0.0278. There are 35 homozygotes in GnomAd4. There are 1574 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 35 gene
