Genes affected

DXO (HGNC:2992): (decapping exoribonuclease) This gene localizes to the major histocompatibility complex (MHC) class III region on chromosome 6. The function of its protein product is unknown, but its ubiquitous expression and conservation in both simple and complex eukaryotes suggests that this may be a housekeeping gene. [provided by RefSeq, Jul 2008]

STK19 (HGNC:11398): (serine/threonine kinase 19) This gene encodes a serine/threonine kinase which localizes predominantly to the nucleus. Its specific function is unknown; it is possible that phosphorylation of this protein is involved in transcriptional regulation. This gene localizes to the major histocompatibility complex (MHC) class III region on chromosome 6 and expresses two transcript variants. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00952 (1451/152390) while in subpopulation AFR AF= 0.033 (1371/41594). AF 95% confidence interval is 0.0315. There are 27 homozygotes in gnomad4. There are 705 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 27 AR gene
