Genes affected

GNL1 (HGNC:4413): (G protein nucleolar 1 (putative)) The GNL1 gene, identified in the human major histocompatibility complex class I region, shows a high degree of similarity with its mouse counterpart. The GNL1 gene is located less than 2 kb centromeric to HLA-E, in the same transcriptional orientation. GNL1 is telomeric to HLA-B and HLA-C. [provided by RefSeq, Jul 2008]

The c.1537C>T (p.R513C) alteration is located in exon 11 (coding exon 11) of the GNL1 gene. This alteration results from a C to T substitution at nucleotide position 1537, causing the arginine (R) at amino acid position 513 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
