WebDNA replication follows base-paring rules: A-T, C-G. Sometimes during DNA replication, a base is inserted, deleted, or substituted with a different one, changing the DNA sequence of a gene. Changes in the DNA sequence of a gene can lead to changes in the protein it codes for. Only mutations in germ cells (eggs or sperm) can be passed to offspring. WebCerebellar ataxia (CA) in the Spinone Italiano is thought to be caused by an intronic GAA repeat expansion in the inositol 1,4,5-trisphosphate receptor, type 1 (ITPR1) gene. The condition is inherited in an autosomal recessive manner, meaning that two copies of the CA allele are needed to develop the disorder.
