IthaID: 3071

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: --235 HGVS Name: NC_000016.10:g.10001_185264del
Hb Name: N/A Protein Info: N/A

Also known as: --175

Comments: The deletion involves the entire α-globin gene cluster. It starts from the telomere (position 60001 bp) to a downstream breakpoint localised to position 235,263 bp (GRCh37.p13). According to the telomere starting site, the duplication spans a smaller region of 175 kb. Heterozygosity for this deletion associated with one functioning α-globin gene, explaining the severe anemia phenotype.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
