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.143A>C (p.D48A) alteration is located in exon 3 (coding exon 3) of the LGALS9C gene. This alteration results from a A to C substitution at nucleotide position 143, causing the aspartic acid (D) at amino acid position 48 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
