Also known as:
Comments: The structural hemoglobin variant of Gγ with two amino acid replacements in cis found in the umbilical cord blood of a neonate in Madrid. The neonate born after a normal 40-week gestation and the main abnormal feature was a decreased MCV of 76 fl, at 1.5 years old. The neonate also carried the –α3.7 deletion.
We follow the HGVS sequence variant nomenclature and IUPAC standards.

Note:
The impact thresholds provided in this section are based on the analyses performed in Tamana et.al. For any given tool, the impact thresholds defined for the set of variants with the same effect on function as the variant examined, are preferred over those defined for the full dataset.
