Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the TFG 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: Neuropathy, hereditary motor and sensory, Okinawa type (HMSNO) [MIM:604484]: A neurodegenerative disorder characterized by young adult onset of proximal muscle weakness and atrophy, muscle cramps, and fasciculations, with later onset of distal sensory impairment. The disorder is slowly progressive and clinically resembles amyotrophic lateral sclerosis. {ECO:0000269|PubMed:22883144, ECO:0000269|PubMed:27813252}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Spastic paraplegia 57, autosomal recessive (SPG57) [MIM:615658]: A complicated form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. Complicated forms are recognized by additional variable features including spastic quadriparesis, seizures, dementia, amyotrophy, extrapyramidal disturbance, cerebral or cerebellar atrophy, optic atrophy, and peripheral neuropathy, as well as by extra neurological manifestations. {ECO:0000269|PubMed:23479643, ECO:0000269|PubMed:27492651, ECO:0000269|PubMed:27813252}.
