Here is a Blue Racer from Iowa

Here is an Artic Ball Python... with a bluish shade
But I can't find anything on cyanomorphic snakes.... sorry

while l was searching the web for cyanomorphic snakes l found this cool picture of The Malayan Blue Coralsnake;


l agree with Claizen that it is genetic,
l couldn't find anything on cyanomorphic snakes.

Very pretty!

Thanks guys for all your help!

I'm not quite fully understanding of how a thing like a mutation could be "spontaneous". Mild break-down in the connection of genetic material?

cyan:a blue-green that is one of the primary pigments
anamorphic:Relating to, having, or producing different optical imaging effects along mutually perpendicular radii: an anamorphic lens

Background: Piebaldism is a rare autosomal dominant disorder of melanocyte development characterized by a congenital white forelock and multiple symmetrical hypopigmented or depigmented macules. This striking phenotype of depigmented patches of skin and hair has been observed throughout history, with the first descriptions dating to early Egyptian, Greek, and Roman writings. Generation after generation demonstrated a distinctive predictable familial mark—a white forelock. Families have sometimes been known for this mark of distinction, carrying such surnames as Whitlock, Horlick, and Blaylock.

The word piebald itself has been attributed to a combination of the "pie" in the magpie (a bird of black and white plumage) and the "bald" of the bald eagle (the United States' national bird, which has a white feathered head).

Piebaldism is due to an absence of melanocytes in affected skin and hair follicles as a result of mutations of the KIT proto-oncogene. As of a 2001 review by Richards et al, 14 point mutations, 9 deletions, 2 nucleotide splice mutations, and 3 insertions of the KIT gene were believed to be mutations causing piebaldism. The severity of phenotypic expression in piebaldism correlates with the site of the mutation within the KIT gene. The most severe mutations seem to be dominant negative missense mutations of the intracellular tyrosine kinase domain, whereas mild piebaldism appears related to mutations occurring in the amino terminal extracellular ligand-binding domain with resultant haplo insufficiency.

Piebaldism is one of the cutaneous signs of Waardenburg syndrome, along with heterochromia of the irides, lateral displacement of inner canthi, and deafness.


Pathophysiology: Piebaldism is an autosomal dominant genetic disorder of pigmentation characterized by congenital patches of white skin and hair that lack melanocytes. Piebaldism results from mutations of the KIT proto-oncogene, which encodes the cell surface receptor transmembrane tyrosine kinase for an embryonic growth factor, steel factor. Several pathologic mutations of the KIT gene now have been identified in different patients with piebaldism. Correlation of these mutations with the associated piebald phenotypes has led to the recognition of a hierarchy of 3 classes of mutations that result in a graded series of piebald phenotypes. KIT mutations in the vicinity of codon 620 lead to the usual phenotype of static piebaldism. Mutations of the KIT proto-oncogene produce variations in phenotype in relation to the site of the KIT gene mutation.

In a recent analysis of 26 unrelated patients with piebaldismlike hypopigmentation (ie, 17 typical patients, 5 patients with atypical clinical features or family histories, and 4 patients with other disorders that involve white spotting), novel pathologic mutations or deletions of the KIT gene were observed in 10 (59%) of the typical patients and in 2 (40%) of the atypical patients. Overall, pathologic KIT gene mutations were identified in 21 (75%) of 28 unrelated patients with typical piebaldism. Patients without apparent KIT mutations had no apparent abnormalities of the gene encoding steel factor itself; however, genetic linkage analyses in 2 of these families implied linkage of the piebald phenotype to KIT. Thus, most patients with typical piebaldism seem to have abnormalities of the KIT gene. A complex network of interacting genes regulates embryonic melanocyte development.

Piebaldism almost always has a static course. Genetic analysis of a mother and daughter with progressive piebaldism revealed a novel Val620Ala (1859T>C) mutation in the KIT gene. This KIT mutation affects the intracellular tyrosine kinase domain and implies a severe phenotype. This is a newly described phenotype with melanocyte instability leading to advancing loss of pigmentation and the progressive appearance of the hyperpigmented macules.

A South African girl of Xhosa ancestry with severe piebaldism and profound congenital sensorineural deafness had a novel missense substitution at a highly conserved residue in the intracellular kinase domain of the KIT proto-oncogene, R796G. Although auditory anomalies in mice with dominant white spotting due to KIT mutations may occur, deafness is not typical in human piebaldism. Thus, sensorineural deafness extends considerably the phenotypic range of piebaldism due to KIT gene mutation in humans and strengthens the clinical similarity between piebaldism and the various forms of Waardenburg syndrome.

Manipulation of the mouse genome may be an important approach for studying gene function and establishing human disease models (Ruan, 2005). Mouse mutants generated and screened for dominant mutations yielded several mice with fur color abnormalities. One causes a phenotype similar to dominant-white spotting (W) allele mutants. This strain may serve as a new disease model of human piebaldism.


Mortality/Morbidity: Piebaldism is a benign disorder.

couldn't find any info on "cyanamorphic" either. However, color variations in all animals are caused by abundance of lack of certain pigments or melanin in the skin of the animal. This is a genetic "defect". The defection is caused by certain sequences of DNA which are not normally active becoming active in the developement of the animal. It is very similar to albinoism, which is a lack of pigmentation in the skin, causing a white-ish color.
From Dictionary.Com

are you sure they said cyanamorphic? that doesn't really fit. unless it refers to the effect that the snake looks blue from a certain angle and green from another, like an optical illusion. That would be caused by a slightly reflective-angled scale color.
