Is deletion a mendelian or mutation
WebDeletions of HBA1 and/or HBA2 tend to underlie most cases of α-thalassemia. The severity of symptoms depends on how many of these genes are lost. Loss of one or two genes is usually asymptomatic, whereas deletion of all four genes is fatal to the unborn child. In contrast, over 100 types of mutations affect HBB, and deletion mutations are rare. WebFrameshift mutation. Insertion or deletion of 1 or more nucleotides shifts the reading frame of the DNA strand. Tay-Sachs Disease. Which disease is an example of a FRAMESHIFT MUTATION involving a 4-base insertion resulting in an altered DNA code leading to formation of a stop codon leading to DECREASED SYNTHESIS of HEXOSAMINIDASE.

WebChromosomal deletion syndromes result from loss of parts of chromosomes. They may cause severe congenital anomalies and significant intellectual and physical disability. Specific chromosomal deletion syndromes are less likely to be suspected prenatally but may be incidentally discovered at that time if karyotyping is done for other reasons.
