Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the GNE gene is commonly pathogenic or not. These statistics are base on transcript: NM_000005476.7. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: Regulates and initiates biosynthesis of N- acetylneuraminic acid (NeuAc), a precursor of sialic acids. Plays an essential role in early development (By similarity). Required for normal sialylation in hematopoietic cells. Sialylation is implicated in cell adhesion, signal transduction, tumorigenicity and metastatic behavior of malignant cells. {ECO:0000250, ECO:0000269|PubMed:10334995}.;
Disease
DISEASE: Sialuria (SIALURIA) [MIM:269921]: In sialuria, free sialic acid accumulates in the cytoplasm and gram quantities of neuraminic acid are secreted in the urine. The metabolic defect involves lack of feedback inhibition of UDP-GlcNAc 2-epimerase by CMP-Neu5Ac, resulting in constitutive overproduction of free Neu5Ac. Clinical features include variable degrees of developmental delay, coarse facial features and hepatomegaly. Sialuria inheritance is autosomal dominant. {ECO:0000269|PubMed:10330343, ECO:0000269|PubMed:10356312, ECO:0000269|PubMed:11326336, ECO:0000269|PubMed:2808337}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Nonaka myopathy (NM) [MIM:605820]: Autosomal recessive muscular disorder, allelic to inclusion body myopathy 2. It is characterized by weakness of the anterior compartment of the lower limbs with onset in early adulthood, and sparing of the quadriceps muscles. As the inclusion body myopathy, NM is histologically characterized by the presence of numerous rimmed vacuoles without inflammatory changes in muscle specimens. {ECO:0000269|PubMed:11528398, ECO:0000269|PubMed:11916006, ECO:0000269|PubMed:12177386, ECO:0000269|PubMed:12325084, ECO:0000269|PubMed:12409274, ECO:0000269|PubMed:12473753, ECO:0000269|PubMed:12473769, ECO:0000269|PubMed:12473780, ECO:0000269|PubMed:12497639, ECO:0000269|PubMed:12811782, ECO:0000269|PubMed:12913203, ECO:0000269|PubMed:15146476}.
