Mention any two autosomal genetic disorders with their symptoms.

The disease is controlled by $Hb^A$ and $Hb^S$ alleles. Homozygous individuals $(Hb^S Hb^S)$ show symptoms,while heterozygous individuals $(Hb^A Hb^S)$ are carriers.
Symptoms: Rapid heart rate,breathlessness,delayed growth,jaundice,weakness,fever,excessive thirst,chest pain,and decreased fertility.
$2$. Down's syndrome: It is an autosomal disorder caused by the trisomy of chromosome $21$.
