OMIA 002148-9615 : Deafness and vestibular dysfunction in Canis lupus familiaris

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 617663 , 613391

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2018

Species-specific name: DINGS

Molecular basis: Guvear et al. (2018): "WGS [whole-genome sequencing of one affected dog] and variant filtering [against 154 normal dogs] identified an alteration in a gene associated with both deafness and vestibular disease in humans: protein tyrosine phosphatase, receptor type Q (PTPRQ). There was a homozygous A insertion at CFA15: 22 989 894, causing a frameshift mutation in exon 39 of the gene. This insertion is predicted to cause a protein truncation with a premature stop codon occurring after position 2054 of the protein sequence that causes 279 Cā€terminal amino acids to be eliminated. "

Prevalence: Guevar et al. (2018): "Prevalence of the variant was 1.5% in a cohort of 202 unaffected Doberman Pinschers; all unaffected Doberman Pinschers were heterozygous or heterozygous for the reference allele."

Breed: Doberman Pinscher.
