Genes affected

CD244 (HGNC:18171): (CD244 molecule) This gene encodes a cell surface receptor expressed on natural killer (NK) cells (and some T cells) that mediate non-major histocompatibility complex (MHC) restricted killing. The interaction between NK-cell and target cells via this receptor is thought to modulate NK-cell cytolytic activity. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Oct 2009]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000704 (107/152022) while in subpopulation SAS AF= 0.0209 (101/4822). AF 95% confidence interval is 0.0176. There are 3 homozygotes in gnomad4. There are 71 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 3 AR gene
