This is a list of variants' phenotypes submitted to
Variants pathogenicity by type
Statistics on ClinVar variants can assist in determining whether a specific variant type in the AMTN 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: Is a promoter of calcium phosphate mineralization, playing a critical role in the formation of the compact, mineralized, aprismatic enamel surface layer during the maturation stage of amelogenesis. {ECO:0000269|PubMed:25407797}.;
- Disease
- DISEASE: Amelogenesis imperfecta 3B (AI3B) [MIM:617607]: An autosomal dominant form of amelogenesis imperfecta, a defect of enamel formation. AI3B is characterized by hypomineralized enamel that has reduced tickness and exhibits structural defects. {ECO:0000269|PubMed:27412008}.
