Also known as:
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.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
