Genes affected
LILRA2 (HGNC:6603): (leukocyte immunoglobulin like receptor A2) This gene encodes a member of a family of immunoreceptors that are expressed predominantly on monocytes and B cells, and at lower levels on dendritic cells and natural killer cells. The encoded protein is an activating receptor that inhibits dendritic cell differentiation and antigen presentation and suppresses innate immune response. Alternatively spliced transcript variants encoding different isoforms have been found. This gene is located in a cluster of related genes on chromosome 19 and there is a pseudogene for this gene on chromosome 3. [provided by RefSeq, Mar 2014]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 2.1253443 fraction of the gene. Cryptic splice site detected, with MaxEntScore 9, offset of 9, new splice context is: tctttgtccaccatccctAGgcc. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
BA1
GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.0643 is higher than 0.05.
