Description

Insertion of a single nucleotide (A) at amino acid position 493 (after the nucleotide string CAATATGCCCTTCCA). This results in the addition of 93 novel amino acids, followed by a premature stop.

Comment:

An insertion of an "A" nucleotide after X:6369067 , in codon 493 of Marf-PB and Marf-PC leads to a frameshift and early termination after 93 novel amino acids.

      Homozygotes die as third instar larvae after an extended larval period of 18-21 days.

      Homozygous clones in the eye result in electroretinogram defects, including a reduction in amplitude.
