Comments: Found in found in a 27-year old pregnant woman with reduced MCV 65 fL, MCH 21.4 pg and HbA 86.5% and increased HbA2 5.4%. Amniocentesis showed that the fetus was compound heterozygous for the novel deletion and the CD 41/42 (‐TTCT) [IthaID: 147], inherited from the father. The woman keeps the fetus and now child shows severe β‐thalassaemia phenotype and needs transfusion therapy every month. The T deletion, causing a frameshift that introduces a premature stop codon two amino acids further down the new reading frame.
