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.218C>T (p.A73V) alteration is located in exon 5 (coding exon 3) of the LGALS8 gene. This alteration results from a C to T substitution at nucleotide position 218, causing the alanine (A) at amino acid position 73 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
