Genetic Variant NEU1:c.352+245_352+247delGGTinsTGA (chr6-31861752-ACC-TCA) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

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

The NM_000434.4(NEU1):c.352+245_352+247delGGTinsTGA variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. It is difficult to determine the true allele frequency of this variant because it is of type MNV, 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

NEU1 (HGNC:7758): (neuraminidase 1) The protein encoded by this gene is a lysosomal enzyme that cleaves terminal sialic acid residues from substrates such as glycoproteins and glycolipids. In the lysosome, this enzyme is part of a heterotrimeric complex together with beta-galactosidase and cathepsin A (the latter is also referred to as 'protective protein'). Mutations in this gene can lead to sialidosis, a lysosomal storage disease that can be type 1 (cherry red spot-myoclonus syndrome or normosomatic type), which is late-onset, or type 2 (the dysmorphic type), which occurs at an earlier age with increased severity.
