Despite these complications, the life expectancy for many individuals can be normal. In childhood, adolescence, and adulthood, decreased life expectancy is likely related to a combination of residual heart defects, infections, aspiration or choking, respiratory issues including obstructive and central apnea, and possibly seizures. Life expectancy highly depends on the severity of manifestations mortality can be high in the first few years when severe birth defects (particularly complex heart defects) are present and often complicated by airway and feeding issues. Following the identification of the genetic cause of CHD7 disorder, the phenotypic spectrum expanded to include cranial nerve anomalies, vestibular defects, cleft lip and/or palate, hypothyroidism, tracheoesophageal anomalies, brain anomalies, seizures, and renal anomalies. The acronym CHARGE refers to a syndrome of unknown cause. CHARGE syndrome is a rare, recently well recognized entity with non-random pattern of congenital anomalies. The mnemonic CHARGE syndrome, introduced in the premolecular era, stands for coloboma, heart defect, choanal atresia, retarded growth and development, genital hypoplasia, ear anomalies (including deafness). Andersen, CHARGE-syndromet1401≥.CHD7 disorder encompasses the entire phenotypic spectrum of heterozygous CHD7 pathogenic variants that includes CHARGE syndrome as well as subsets of features that comprise the CHARGE syndrome phenotype. Cranial nerve abnormalities in people with CHARGE syndrome include: Total loss or reduced sense of smell (anosmia): 90100 of people. ![]() in American Journal of Medical Genetics Part C: Seminars in Medical Genetics. Underdeveloped genitals are a tell-tale sign of CHARGE in males, but not so much in females. American journal of medical genetics Part A, 2010.

Genetic consultation should be requested for patients with characteristic CHARGE syndrome features, even if not all major features are present. In our case, other features of the syndrome were observed. Some of the major findings such as coloboma and choanal atresia may not be present in some cases with a genetic mutation. Because of delayed puberty and hypogonadotropic hypogonadism, choriogonadotropin alfa was started.Ĭonclusion: In CHARGE syndrome, neural crest-derived organ anomalies develop due to mutations in the CHD7 gene. Gnl 171Ter) was detected in a genetic examination. At the age of 18, a heterozygous mutation in the CHD7 gene (p. Pubic and axillary hair growth was insufficient. He had a short neck, an atypical facial appearance, prominent auricles, abnormal ears, short philtrum, low nuchal hairline, mild kyphoscoliosis, gynecomastia, and micro genitalia. In physical examination, his final height was 172 cm. choanal atresia, cranial nerve abnormalities, and a characteristic CHARGE syndrome ear. In his family history, there were consanguinity and suspicious deaths in his siblings. CHARGE syndrome describes clusters of birth defects in children, including coloboma (eye), heart defects of any type, atresia (choanal), and more. ![]() ![]() Hypogonadotropic hypogonadism was found with micro genitalia. Orchiopexy was performed at 2-3 years because of his undescended testis. Block appearance was detected in the cervical vertebrae. His neurological development was retarded. CHARGE syndrome is a genetic disorder characterized by a specific and a recognizable pattern of anomalies, namely, Coloboma, Heart defects, Atresia of choana, Retardation of growth and/or development, Genitourinary defects, and Ear anomalies and/or deafness. Inner and outer ear anomalies and mixed hearing loss were present. Other upper airway abnormalities that can be seen in CHARGE syndrome include: laryngomalacia, tracheomalacia, tracheoesophageal fistula, and subglottic stenosis. He was operated because of vascular ring compression on his esophagus. Approximately 65 of patients with CHARGE syndrome may have obstructed breathing due to choanal atresia at birth. Objective: Here, a case of CHARGE syndrome, which had no ocular coloboma and choanal atresia findings but had other features and was diagnosed genetically at a late age, was discussed.Ĭase: The 20-year-old male patient who had no problems during delivery had recurrent pneumonias. The disease has four major findings expressed as 4C ocular coloboma, choanal atresia, cranial nerve abnormalities, and characteristic ear anomalies. The name reflects the initials of the clinical findings (Coloboma, Heart disease, Atresia of the choanae, Retarded growth and mental development, Genital anomalies, Ear malformations, and hearing loss). Background: CHARGE Syndrome is a rare inherited congenital disorder.
