The passage below is from ‘the Blank Slate’ by Steven Pinker.
http://evolbiol.ru/blankslate/blankslate.htm
A promising example is the F0XP2 gene, associated with a speech and language disorder in a large family. The aberrant nucleotide has been found in every impaired member of the family (and in one unrelated person with the same syndrome), but it was not found in any of the unimpaired members, nor was it found in 364 chromosomes from unrelated normal people. The gene belongs to a family of genes for transcription factors — proteins that turn on other genes — that are known to play important roles in embryogenesis. The mutation disrupts the part of the protein that latches onto a particular region of DNA, the key step in turning on the right gene at the right time.
In this passage, ‘The aberrant nucleotide,’ ‘The gene,’ and ‘The mutation,’ seem to refer to ‘the F0XP2 gene.’
Am I right?
Regards.

Stenka25 The aberrant nucleotide One of the four nucleotides (A, C, G, T) is wrong. This is the aberrant nucleotide. It takes a very great many nucleotides to make the whole gene, and only this one nucleotide is abnormal.

- This is the aberrant nucleotide.
- It takes a very great many nucleotides to make the whole gene, and only this one nucleotide is abnormal.
- That alone causes the gene to malfunction.
- Stenka25 The gene Yes.

Stenka25The geneYes. That's a reference to the gene mentio

Stenka25Thanks a lot as always, CJ.You're welcome.
By the way, it's not F0XP2 (which contains a zero); it's FOXP2 (which contains the letter "O").
Check out this link if you want to see the whole sequence of nucleotides of the FOXP2 gene. The mutation Pinker is talking about is a change in just one of those letters! No, I don't know

Thanks a lot for everything, CJ.
It really is confusing, that sequence of the gene!
