Genetic Variant ASNS:c.-60+40_-60+41insCTGCGCCCCGCGCCCTGCGCCCCGCGCCCTGCGCCCCGCGCC (chr7-97872310-T-TGGCGCGGGGCGCAGGGCGCGGGGCGCAGGGCGCGGGGCGCAG) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

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

The NM_001673.5(ASNS):c.-60+40_-60+41insCTGCGCCCCGCGCCCTGCGCCCCGCGCCCTGCGCCCCGCGCC variant causes a intron 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

ASNS (HGNC:753): (asparagine synthetase (glutamine-hydrolyzing)) The protein encoded by this gene is involved in the synthesis of asparagine. This gene complements a mutation in the temperature-sensitive hamster mutant ts11, which blocks progression through the G1 phase of the cell cycle at nonpermissive temperature. Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, May 2010]
