frameshift mutation

(redirected from frameshift mutations)

read·ing-·frame·shift mu·ta·tion

a mutation that results from insertion or deletion of a single nucleotide into, or from, the normal DNA sequence; because the genetic code is read three nucleotides at a time, all nucleotide triplets distal to the mutation will be one step out of phase and misread, and hence translated as different amino acids.

frameshift mutation

(frām′shĭft′)
n.
A mutation in a DNA chain that occurs when the number of nucleotides inserted or deleted is not a multiple of three, so that every codon beyond the point of insertion or deletion is read incorrectly during translation.

frameshift mutation

The deletion or insertion of one or two DNA nucleotides that alters the transcription of each subsequent triplet.

C, Next-generation sequencing identified the presence of both N-terminal frameshift mutation (CEBPA c.68_78delCGCACGCGCCC, p.Pro23fs; variant allele fraction 47%) and Cterminal in-frame deletion (CEBPA c.914_916delAGC, p.Gln305del; variant allele fraction 32%) D, Flow cytometric analysis reveals blasts with aberrant CD7 expression (Wright-Giemsa, original magnification X1000 [A]; hematoxylin-eosin, original magnification X600 [B]).
Likewise, the present study also identified similar results as in previous studies in 3 MFS pedigrees with frameshift mutations, thereby contributing to the extension of the known mutational spectrum of frame-shift, for understanding the genotype-phenotype correlations in cardiovascular involvement.
Most of the detected mutations were missense mutations (26), 5 were splice defects, 6 were nonsense, and 3 were frameshift mutations (Table 1).
