Genes affected
ICAM4 (HGNC:5347): (intercellular adhesion molecule 4 (Landsteiner-Wiener blood group)) This gene encodes the Landsteiner-Wiener (LW) blood group antigen(s) that belongs to the immunoglobulin (Ig) superfamily, and that shares similarity with the intercellular adhesion molecule (ICAM) protein family. This ICAM protein contains 2 Ig-like C2-type domains and binds to the leukocyte adhesion LFA-1 protein. The molecular basis of the LW(A)/LW(B) blood group antigens is a single aa variation at position 100; Gln-100=LW(A) and Arg-100=LW(B). Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]
ICAM4-AS1 (HGNC:55990): (ICAM4 antisense RNA 1)
LIMASI (HGNC:56357): (lncRNA inflammatory and mucous response associated, antisense to ICAM1)

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.2759463 fraction of the gene. Cryptic splice site detected, with MaxEntScore 3.7, offset of -36, new splice context is: tggagcctccggtcttaaAGggc. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
BP6
Variant 19-10287612-G-T is Benign according to our data. Variant chr19-10287612-G-T is described in ClinVar as Likely_benign. ClinVar VariationId is 3527397.Status of the report is criteria_provided_single_submitter, 1 stars.
