Links to MONDO diseases: No links.

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2015

Cross-species summary: Also called feather-crested head.

Molecular basis: Vickrey et al. (2015) "identified a G to A mutation in the sixth exon of EphB2 of crested birds (cr dove); this change is predicted to result in a glycine to arginine amino acid substitution at position 636 of the protein (Gly636Arg)"
