Cholinergic receptor, nicotinic, epsilon (CHRNE) - coding DNA reference sequence

(used for mutation description)

(last modified December 30, 2011)


This file was created to facilitate the description of sequence variants in the CHRNE gene based on a coding DNA reference sequence following the HGVS recommendations. The sequence was taken from NG_008029.2, covering CHRNE transcript NM_000080.3. The protein is N-terminally cleaved to obtain the mature CHRNE protein, removing the signal peptide (amino acids 1-20). Publications describing variants in CHRNE originally used the mature protein as a reference.
CHRNE intron 8 contains the C17ORF107 gene (transcribed from the other strand). The end of CHRNE gene overlaps with 3' end of the MINK1 gene (transcribed from other strand).

Please note that introns are available by clicking on the exon numbers above the sequence.

 (downstream sequence)
Legend:
Nucleotide numbering (following the rules of the HGVS for a 'Coding DNA Reference Sequence') is indicated at the right of the sequence, counting the A of the ATG translation initiating Methionine as 1. Every 10th nucleotide is indicated by a "." above the sequence. The Cholinergic receptor, nicotinic, epsilon protein sequence is shown below the coding DNA sequence, with numbering indicated at the right starting with 1 for the translation initiating Methionine. Every 10th amino acid is shown in bold. The position of introns is indicated by a vertical line, splitting the two exons. The start of the first exon (transcription initiation site) is indicated by a '\', the end of the last exon (poly-A addition site) by a '/'. The exon number is indicated above the first nucleotide(s) of the exon. To aid the description of frame shift mutations, all stop codons in the +1 frame are shown in bold while all stop codons in the +2 frame are underlined.
