OMIA:002229-103584 : Hypotrichosis, HR-related in Delphinus capensis (long-beaked common dolphin)

In other species: domestic cat , bottlenosed dolphin , beluga whale , minke whale , pig , sheep , Indo-Pacific finless porpoise , Yangtze River dolphin , Omura's baleen whale

Categories: Integument (skin) phene

Links to possible relevant human trait(s) and/or gene(s) in OMIM: 203655 (trait) , 602302 (gene)

Mendelian trait/disorder: unknown

Considered a defect: no

Year key variant first reported: 2013

Cross-species summary: Also known as Hairless

Molecular basis: Chen et al. (2013) reported evidence that the HR gene in cetaceans, including Delphinus capensis, has degenerated into a non-functional pseudogene, which is consistent with the hairlessness of this species.
