Genes affected

LGALS9B (HGNC:24842): (galectin 9B) This gene was initially thought to represent a pseudogene of galectin 9; however, this transcript has good exon-intron structure and encodes a predicted protein of the same size as and highly similar to galectin 9. This gene is one of two similar loci on chromosome 17p similar to galectin 9 and now thought to be protein-encoding. This gene is the more centromeric gene. [provided by RefSeq, Jul 2008]

The c.451C>G (p.R151G) alteration is located in exon 5 (coding exon 5) of the LGALS9B gene. This alteration results from a C to G substitution at nucleotide position 451, causing the arginine (R) at amino acid position 151 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
