Biologically Significant Variants Click here for help
Type:  Single nucleotide polymorphism
Species:  Human
Amino acid change:  K77R
Global MAF (%):  1
Subpopulation MAF (%):  AFR|AMR|ASN|EUR: 14|6|17|3
Minor allele count:  C=0.099/216
SNP accession: 
Validation:  1000 Genomes, Frequency
Biologically Significant Variant Comments
The RefSeq gene (Gene ID:11245) has 3 coding exons, first contains most of TM 1, second contains most of TMs 2 and 3. There are a number of cDNAs which insert an extra 58 base exon between exons 1 and 2 and then use a compensating shorter (by 61 bases at acceptor end) version of exon 2. These alternate splice variants seem to be associated with one allele of the SNP rs66490630 which is the last base of the extra exon.
