IthaID: 3764

Names and Sequences

Functionality:	Globin gene causative mutation	Pathogenicity:	N/A
Common Name:	-4 G>C	HGVS Name:	HBA1:c.-41C>G
Hb Name:	N/A	Protein Info:	N/A
Also known as:

We follow the HGVS sequence variant nomenclature and IUPAC standards.

Context nucleotide sequence:
GCATAAACCCTGGCGCGCTCGCGGGC [C/G] GGCACTCTTCTGGTCCCCACAGACTCA (Strand: +)

Comments: The substitution reported in a 17-year old male with Hb 14.4 g/dL, MCV 77.2 fL, MCH 24.2 pg, RBC 5.96 10^12/L and RDW 13.2 % with normal HbA2 value. GAP-PCR showed presence of two abnormal bands around 3.7 gene deletion. Molecular analysis showed the substitution C>G at both HbA1 and HbA2 regions.
