Genes affected

LTA (HGNC:6709): (lymphotoxin alpha) The encoded protein, a member of the tumor necrosis factor family, is a cytokine produced by lymphocytes. The protein is highly inducible, secreted, and forms heterotrimers with lymphotoxin-beta which anchor lymphotoxin-alpha to the cell surface. This protein also mediates a large variety of inflammatory, immunostimulatory, and antiviral responses, is involved in the formation of secondary lymphoid organs during development and plays a role in apoptosis. Genetic variations in this gene are associated with susceptibility to leprosy type 4, myocardial infarction, non-Hodgkin's lymphoma, and psoriatic arthritis. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Jul 2012]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0394 (5986/151752) while in subpopulation AFR AF = 0.0356 (1473/41372). AF 95% confidence interval is 0.0341. There are 232 homozygotes in GnomAd4. There are 3303 alleles in the male GnomAd4 subpopulation. Median coverage is 29. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 232 gene
