Single nucleotide deletion in exon 22 of btv. This results in a frameshift and a premature stop codon.
btvk07109b is likely a "hit and run" lesion. It is not associated with the 'k07109b' insertion of the P{lacW} element, which is actually present in the Fas3 gene, nearby.
A single base deletion was reported at 2L:17966613 within the btv coding region that leads to a frameshift and early translation termination.
abdominal lateral pentascolopidial chordotonal organ lch5 & scolopidium
The arrangement and numbers of scolopidia in the abdominal lateral pentascolopidial chordotonal organs of these larvae are normal. However, these scolopidia have significant morphological defects, both in their outer dendritic segments and ciliary dilation. btvk07109b homozygous larvae have reduced touch sensitivity compared to wild-type. Locomotion in these larvae is aberrant: compared to controls they larvae are slower and pause, turn and retreat more often. These defects in locomotion arise at least partially from defective peristaltic motion: maximum larval length, stride period and % positive and negative flow are all defective. Despite their locomoter defects, these larvae exhibit normal phototaxic behaviour.
Separable from: P{lacW}Fas3k07109b.
