Also known as:
Comments: AC deletion at the -2 and -3 positions preceding the initiation codon (ATG) found on a chromosome that carries the -3.7 kb deletion (-α3.7). HGVS name reports deletion breakpoints in -α3.7 (type I) [IthaID: 300] and should be used with caution.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
