IthaID: 3698

Names and Sequences

Functionality: Disease modifying mutation Pathogenicity: N/A
Common Name: rs16998911 HGVS Name: NG_016419.1:g.49280T>C

Context nucleotide sequence:

Also known as:

Comments: Significant association with high F cell numbers (in the range of 13 to 30%) and HbF levels (>4%) in males with sickle cell disease from Tanzania. The association was not replicated in female patients. rs16998911 is an X-linked determinant of Fcells% also explaining gender differences in F-cell distribution in SCD patients.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
