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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2024The c.621G>A (p.M207I) alteration is located in exon 7 (coding exon 7) of the LGALS9B gene. This alteration results from a G to A substitution at nucleotide position 621, causing the methionine (M) at amino acid position 207 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
