can you please help me out with this ?

Mutations in the IL2RG gene cause approximately 30 percent of

severe combined immunodeficiency disorder (SCID) cases in

humans. These mutations result in alterations to a protein component

of cytokine receptors that are essential for proper development

of the immune system. The IL2RG gene is composed of

eight exons and contains upstream and downstream sequences

that are necessary for proper transcription and translation. Below

are some of the mutations observed. For each, explain its likely

influence on the IL2RG gene product (assume its length to be

375 amino acids).

 

  1. Nonsense mutation in a coding region

 

  1. Insertion in Exon 1, causing frameshift

 

  1. Insertion in Exon 7, causing frameshift

 

  1. Missense mutation

 

  1. Deletion in Exon 2, causing frameshift

 

  1. Deletion in Exon 2, in frame

 

(g) Large deletion covering Exons 2 and 3
