Genes affected
ALMS1 (HGNC:428): (ALMS1 centrosome and basal body associated protein) This gene encodes a protein containing a large tandem-repeat domain as well as additional low complexity regions. The encoded protein functions in microtubule organization, particularly in the formation and maintanance of cilia. Mutations in this gene cause Alstrom syndrome. There is a pseudogene for this gene located adjacent in the same region of chromosome 2. Alternative splice variants have been described but their full length nature has not been determined.

Likely benign, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJan 08, 2018p.Lys3900Arg in exon 18 of ALMS1: This variant is not expected to have clinical significance due to a lack of conservation across species, including mammals. Of note, 4 have an Arginine (Arg) at this position despite high nearby amino acid conservation. In addition, computational prediction tools do not suggest an impa ct to the protein.
