Single nucleotide deletion (G) at position 2070 in the ovo-RA reading frame. This is in the extended exon 3 of ovo, before the splice site. The mutation is expected to result in a frameshift and early stop codon 15 codons downstream, but only in isoforms containing the exon 3 extension.
Deletion of a "G" base leads to a frameshift and early translation termination 15 codons downstream, but only in isoforms containing the exon 3 extension.
