IthaID: 2210



Names and Sequences

Functionality: Globin gene causative mutation
Common Name: CD 31 AGG>CGG [Arg>Arg] HGVS Name: HBA2:c.94A>C
Hb Name: N/A Protein Info: N/A

Comments: Experimental analysis showed utilization of a cryptic splice site at codon 15 that resulted in an aberrant splice variant. As a result, a frameshift in the reading frame of the mature mRNA was produced, leading to the formation of a premature termination codon between codons 48 and 49 in exon 2.
