ALMS1 gene

The gene ALMS1 is involved in autosomal recessive Alstrom syndrome.

Epidemiology

The estimated prevalence of Almstöm syndrome is <1:100,000.[Error: Macro 'ref' doesn't exist]

Phenotype

The full-blown clinical picture is present only if two mutated alleles are present. Though a typical recessive disease, some clinical feature might be present in heterozygous carries too. These include obesity, dyslipidemia rich in triglycerides and type 2 diabetes melitus.
