OMIA:002174-9615 : Hypothyroidism, congenital dyshormonogenic, with goiter, SLC5A5-related in Canis lupus familiaris (dog)

Categories: Endocrine / exocrine gland phene (incl mammary gland)

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 274400 (trait) , 601843 (gene)

Links to MONDO diseases:

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 symbol: CDHG

Inheritance: Soler Arias et al. (2018): "Congenital dyshormonogenic hypothyroidism with goiter in this family [of Shih-Tzu] is an autosomal recessive trait."

Molecular basis: Soler Arias et al. (2018): "A homozygous mutation of the intron 9 splice acceptor site of SLC5A5 gene, encoding the sodium/iodine symporter (NIS), was found in the DNA of one of the affected dogs [the only one from whom a DNA sample could be obtained; the other one having died]. The mutation was a single base transition of guanine > adenine (G > A) at position 45,024,672 of dog chromosome 20 (CFA20). Five of eight healthy dogs, including both parents of one of the dogs exhibiting CDHG, were heterozygous A/G, and the other 3 were homozygous for the wild-type allele G/G. No sequence variant was found in thyroid peroxidase of the affected dog [for which a DNA sample was available]."

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing

Clinical features: Soler Arias et al. (2018): "The ITD was recognized by the absence of uptake of technetium-99m in the salivary glands (sg) and goiter observed by scintigraphy. In the same scan, radiopharmaceutical uptake was found in the anterior mediastinum of both [affected] dogs and in the right axillary lymph node in the oldest dog. A follicular thyroid carcinoma was diagnosed by histopathology after thyroidectomy of the older dog. An adenomatous goiter with ectopic thyroid tissue, and degenerative changes in myocardium were the findings after necropsy in the youngest dog."

Breed: Shih Tzu (Dog) (VBO_0201223).

Variants

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.

Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
