IthaID: 3275

Names and Sequences

Functionality:	Globin gene causative mutation	Pathogenicity:	N/A
Common Name:	(αα)ALT	HGVS Name:	NC_000016.10:g.103193_106553delins35
Hb Name:	N/A	Protein Info:	N/A

Also known as:

Comments: The deletion removes only the the major α-globin regulatory element MCS-R2 (HS-40 site). The deletion extends from position chromosome 16g.103,193 to 106,553 removing 3361 bp. In addition, an insertion of 39 bp bridging the deletion breakpoints was observed possibly resulting from a complex rearrangement involving two fragments of DNA from chromosome 3.
