Genes affected

LGALS9C (HGNC:33874): (galectin 9C) 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 telomeric gene. [provided by RefSeq, Jul 2008]

The c.819T>G (p.F273L) alteration is located in exon 10 (coding exon 10) of the LGALS9C gene. This alteration results from a T to G substitution at nucleotide position 819, causing the phenylalanine (F) at amino acid position 273 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
