Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the COG6 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.

• Function: FUNCTION: Required for normal Golgi function. {ECO:0000250}.
• Disease: DISEASE: Congenital disorder of glycosylation 2L (CDG2L) [MIM:614576]: A multisystem disorder caused by a defect in glycoprotein biosynthesis and characterized by under-glycosylated serum glycoproteins. Congenital disorders of glycosylation result in a wide variety of clinical features, such as defects in the nervous system development, psychomotor retardation, dysmorphic features, hypotonia, coagulation disorders, and immunodeficiency. The broad spectrum of features reflects the critical role of N- glycoproteins during embryonic development, differentiation, and maintenance of cell functions. Clinical features of CDG2L include neonatal intractable focal seizures, vomiting, loss of consciousness, intracranial bleeding due to vitamin K deficiency, and death in infancy. {ECO:0000269|PubMed:20605848}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Shaheen syndrome (SHNS) [MIM:615328]: An autosomal recessive form of syndromic mental retardation. Affected individuals show severe intellectual disability, hypohidrosis, dental enamel hypoplasia, and hyperkeratosis of the palms and soles. Some may develop mild microcephaly. {ECO:0000269|PubMed:23606727}. Note=The disease is caused by mutations affecting the gene represented in this entry.
