Genes affected

LGALS8 (HGNC:6569): (galectin 8) This gene encodes a member of the galectin family. Galectins are beta-galactoside-binding animal lectins with conserved carbohydrate recognition domains. The galectins have been implicated in many essential functions including development, differentiation, cell-cell adhesion, cell-matrix interaction, growth regulation, apoptosis, and RNA splicing. This gene is widely expressed in tumoral tissues and seems to be involved in integrin-like cell interactions. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

The c.973A>G (p.N325D) alteration is located in exon 12 (coding exon 10) of the LGALS8 gene. This alteration results from a A to G substitution at nucleotide position 973, causing the asparagine (N) at amino acid position 325 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
