A mutation occurs in which a base (T) is inserted into the DNA sequence after the G, at the position marked with an asterisk, be
Zarrin [17]

A mutation which occurs when a base is introduced into the DNA sequence before transcription begins will lead to frame-shift of a single base on the DNA sequence resulting in nonfunctional protein from the transcribed mRNA.

Explanation:

This change either through addition or deletion of a single base in the codon sequences of the DNA will modify the amino acid codes and will result in nonfunctional proteins after transcription.

This mutation will just result in change of a single base, i.e., it would be added either to the enhancer region or the silencer region of the sequence before the promoter which initiates transcription.

The mRNA produced due to mutated DNA sequence after the deletion or insertion point will be read as out of frame thus resulting in nonsense protein.

A patient has an inherited defect in the liver enzyme fructose 1,6-bisphosphatase and this results in an abnormally high levels
DedPeter [7]

If the live enzyme fructose 1,6- bisphosphatase defect is occured and this results in an abnormally high levels of lactate in the blood plasme this will result into the lactate will accumulate into the blood.

What is the work of fructose 1,6-biphosphatase enzyme?

In the liver, gluconeogenesis converts lactate to glucose. If FBPase-1 is defective, lactate cannot enter the gluconeogenic pathway in hepatocytes, building up in the blood.

A crucial enzyme in gluconeogenesis is fructose 1,6-bisphosphatase (FBPase). It is a possible target for drugs used to treat type II diabetes. Additionally, the protein is linked to a rare genetic metabolic disorder, and certain cancer cells lack the activity of the enzyme FBPase, which encourages glycolysis and aids in the Warburg effect.
