Variants pathogenicity by type
Statistics on ClinVar variants can assist in determining whether a specific variant type in the HK1 gene is commonly pathogenic or not.
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.

- Disease
- DISEASE: Hexokinase deficiency (HK deficiency) [MIM:235700]: Rare autosomal recessive disease with nonspherocytic hemolytic anemia as the predominant clinical feature. {ECO:0000269|PubMed:12393545, ECO:0000269|PubMed:7655856}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Neuropathy, hereditary motor and sensory, Russe type (HMSNR) [MIM:605285]: An autosomal recessive progressive complex peripheral neuropathy characterized by onset in the first decade of distal lower limb weakness and muscle atrophy resulting in walking difficulties. Distal impairment of the upper limbs usually occurs later, as does proximal lower limb weakness. There is distal sensory impairment, with pes cavus and areflexia. Laboratory studies suggest that it is a myelinopathy resulting in reduced nerve conduction velocities in the demyelinating range as well as a length-dependent axonopathy. {ECO:0000269|PubMed:19536174}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Retinitis pigmentosa 79 (RP79) [MIM:617460]: A form of retinitis pigmentosa, a retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. RP79 inheritance is autosomal dominant. {ECO:0000269|PubMed:25190649, ECO:0000269|PubMed:25316723}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
