A deletion of six bp from base pair 104 to 109, resulting in a two amino acid deletion just upstream the predicted methyltransferase signatures (at positions 36 and 37). These two amino acids are conserved from flies to human.
In frame 6bp deletion leading to the deletion of two Ala residues at positions 36 and 37, PHIAACMAH to PHICMAH.
Mettl5Δ2AA/Mettl5Δ2AA adults exhibit a mild angular deviation from the walking tracks.
