Flies are uncoordinated showing frequent leg crossing and wings held up or out. Walking and righting ability is impaired. Spontaneous or induced (by light or mechanical stimuli) activity is vigorous. Mechanoreceptor potentials are reduced or absent in thoracic macrochaete bristles. The sound evoked response (measured via the antennal nerve) is somewhat reduced. ERGs are normal.
Embryos do not exhibit any cuticular abnormalities.
Due to a naming clash that goes back many years, two different alleles of nompC, with contrasting molecular lesions, were named nompC[1]. Thanks to user input, we have been able to disambiguate these two alleles. They are now called nompC[1] and nompC[a1]. The nompC[1] allele was generated in the Zuker lab by EMS (FBrf0127378). The nompC[a1] allele was made by Szidonya and Reuter (FBrf0047784) and published in 1988 as jf24[a1]. Allele jf24[a1] was renamed in Lindsley and Zimm 1992 (p. 353) as l(2)25Dc[1]. Allele l(2)25Dc[1] subsequently became nompC[1] based on a foot note in Kernan et al., 1994 (FBrf0073546) identifying l(2)25Dc as nompC. The references and data for jf24[a1]/l(2)25Dc[1]/nompC[1] have now been split from the nompC[1] FlyBase record and are associated with allele nompC[a1].
