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.

Potent mutations in ALMS1 are associated with a rare condition called Alstrom syndrome. It can cause excessive eating, insulin resistance. However, no evidence is found to ascertain the role of rs45501594 in Alstrom syndrome yet. -

Variant summary: The ALMS1 c.10625C>G (p.Thr3542Ser, alternative name c.10631C>G) variant involves the alteration of a non-conserved nucleotide. 4/5 in silico tools predict a benign outcome for this variant. This variant was found in 824/119494 control chromosomes (5 homozygotes), predominantly observed in the European (Non-Finnish) subpopulation at a frequency of 0.0099462 (658/66156). This frequency is about 4 to 7 times the estimated maximal expected allele frequency of a pathogenic ALMS1 variant (0.0022361) for CYMO or Alstrom Syndrom, respectively. The allele frequency in the European (Non-Finnish) subpopulation suggests that this variant is likely a benign polymorphism found primarily in the populations of European (Non-Finnish) origin. The variant has been reported in patients with clinical features of Alstrom Syndrome, but without evidence of causality (ie co-segregation or functional studies). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. Taken together, this variant is classified as benign. -

Significance:Benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
