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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 14, 2024The c.754G>A (p.V252I) alteration is located in exon 6 (coding exon 6) of the GNL1 gene. This alteration results from a G to A substitution at nucleotide position 754, causing the valine (V) at amino acid position 252 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
