AMMECR1

protein-coding

AMMECR nuclear protein 1, the group of Small nucleolar RNA protein coding host genes

Gene summary

The exact function of this gene is not known, however, submicroscopic deletion of the X chromosome including this gene, COL4A5, and FACL4 genes, result in a contiguous gene deletion syndrome, the AMME complex (Alport syndrome, mental retardation, midface hypoplasia, and elliptocytosis). Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2010]

ClinVar Variants & Pathogenicity by Type

Statistics based on transcript NM_015365.3. Only rare variants are included.

We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.

Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.

Variable clinical features include anemia, and mild early motor or speech delay. {ECO:0000269|PubMed:27811305, ECO:0000269|PubMed:28089922}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Alport syndrome with mental retardation, midface hypoplasia and elliptocytosis (ATS-MR) [MIM:300194]: A X-linked contiguous gene deletion syndrome characterized by glomerulonephritis, sensorineural hearing loss, mental retardation, midface hypoplasia and elliptocytosis. {ECO:0000269|PubMed:10049589}. Note=The gene represented in this entry may be involved in disease pathogenesis.;
