Genetic Variant LGALS8:c.*2836_*2849dupAAAAAAAAAAAAAA (chr1-236550992-T-TAAAAAAAAAAAAAA) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.

The NM_201544.4(LGALS8):c.*2836_*2849dupAAAAAAAAAAAAAA variant causes a 3 prime UTR change involving the alteration of a non-conserved nucleotide. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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]

LGALS8 links:

HEATR1 (HGNC:25517): (HEAT repeat containing 1) Enables RNA binding activity. Involved in positive regulation of rRNA processing and positive regulation of transcription by RNA polymerase I. Located in fibrillar center and mitochondrion. Implicated in pancreatic ductal carcinoma. Biomarker of glioblastoma. [provided by Alliance of Genome Resources, Apr 2022]
