SCC malformations are mostly reported in congenital syndromes with multiple deformities such as coloboma, heart defects, atresia choanae, growth retardation, genital abnormalities, and ear abnormalities syndrome.
As an abbreviation CHARGE stands for: coloboma, heart defects, atresia choanae, and retardation of growth, genital, and ear abnormalities.
The acronym CHARGE stands for coloboma, heart defects, atresia choanae, retarded growth and development, genital hypoplasia, and ear anomalies and deafness (Blake, Salem-Hartshorne, Daoud, & Gradstein, 2005).
8%) had Grade III adenoids (Enlarged adenoids filling from 2/3rd of vertical portion of choanae to nearly complete obstruction).
The anterior nares were slit like opening whereas choanae were beak shaped opening.
Two subsequent attempts made at 3-week intervals were both unsuccessful; the rhinolith was too large to remove through the nostril or posterior choanae.
Whole genome "jumping libraries" of a prenatal sample identified a translocation breakpoint that disrupted chromodomain helicase DNA binding protein 7 (CHD7), a causal locus in the CHARGE syndrome (coloboma of the eye, heart defects, atresia of the choanae, retardation of growth and/or development, genital and/or urinary abnormalities, and ear abnormalities and deafness), otherwise unidentifiable with current screening technology, the knowledge of which assists with prenatal counseling (68).
Vomerine teeth in two small oblique groups, are closer to each other than to choanae.
These are: C: Coloboma of the eye, central nervous system anomalies; H: Heart defects; A: Atresia of the choanae R: Retardation of growth and/or development G: Genital and/or urinary defects (Hypogonadism) E: Ear anomalies and/or deafness.
Examination of the oral and nasal cavities while the animal was anesthetized revealed mucous entering the oral cavity through the nasal choanae and hyperemic nasal mucosa.
CHARGE: Coloboma of the eye, Heart defects, Atresia of the choanae, severe Retardation of growth and development, Genital abnormalities, and Ear abnormalities
SCID variants include cartilage-hair hypoplasia, CHARGE syndrome (coloboma, heart defect, atresia choanae [also known as choanal atresia], retarded growth and development, genital abnormality, and ear abnormality), Down syndrome, or DiGeorge syndrome.
