Trooper mice harbour an intronic point mutation in Chd7. (A) 20 F1N1 mice were classified as hearing impaired following click-ABR testing (threshold ≥45 dB SPL). SNP Haplotypes for the proximal region of chromosome 4 are illustrated, with the numbers below each haplotype representing the number of mice observed with that haplotype. The region between the centromere and rs13477553 was heterozygous in all hearing impaired mice. (B) DNA sequence electropherograms of a region of Chd7 intron 9 in two hearing impaired Trooper mice and an unaffected littermate. Both affected mice were heterozygous for a c.3219-18T> A mutation in Chd7, which was predicted to affect splicing.
