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]

Apr 07, 2022

The c.995G>C (p.R332P) alteration is located in exon 11 (coding exon 11) of the LGALS9B gene. This alteration results from a G to C substitution at nucleotide position 995, causing the arginine (R) at amino acid position 332 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
