  • Patterned atrophoderma occurs in the areas of scaling and is thought to be caused by inflammation and hyperkeratosis in the newborn. Ichthyosis usually appears in older children or adults, although occurrence in newborns has also been reported.[dermatologyadvisor.com]
  • Although the eruption usually resolves during infancy, older children may subsequently develop inflammation and wasting (atrophy) of follicles (follicular atrophoderma), causing pores to appear unusually large.[rarediseases.org]
Weakness
  • Affected males suffer from weak muscle tone, changes in the structure of the brain, moderate to severe delay in development, seizures, distinctive facial features, and other birth defects.[conradihunermannsyndrome.weebly.com]
Saddle Nose
  • The disorder recognized by Hünermann also included micromelia, a saddle nose deformity, flexion contractures, cataracts, and a dermopathy.[mhmedical.com]
  • The severe form is characterised by marked congenital rhizomelic dwarfism, flexion contractures of large joints, small chest and saddle nose deformity. Asymmetrical limb shortening and kyphoscoliosis become prominent with age.[ijri.org]
Failure to Thrive
  • This is the only manifestation in most patients with HIDS, and, in the case of classical mevalonic aciduria, is part of a severe multisystemic disease, including malformations, severe failure to thrive and neurological abnormalities.[thieme-connect.com]

  • Affected infants may fail to grow and gain weight at the rate expected for age and gender (failure to thrive). Growth deficiencies may ultimately result in a final adult height that is below normal (short stature).[rarediseases.org]
Alopecia
  • Scalp involvement results in patchy, scarring alopecia.[escholarship.org]
  • Short stature in combination with ichthyosis or alopecia, cataracts, and limb shortening in an adult should prompt consideration of a diagnosis of CDPX2.[jhu.pure.elsevier.com]
  • When examined, the mother had linear alopecia, said to have been present from birth. She also had ichthyosis during childhood and a difference in leg length for which she had undergone several orthopaedic corrections.[ntvg.nl]
  • A 5-year-old girl presented for evaluation of ill-defined patches of cicatricial alopecia. In addition, subtle follicular atrophoderma, esotropia, craniofacial asymmetry and short stature were noted.[ncbi.nlm.nih.gov]

Dry, Scaly Skin
  • Management of the patient’s dry, scaly skin has included daily application of ammonium lactate 12 percent cream, ceramide-enriched emollients, and petrolatum ointment.[escholarship.org]
Hypopigmented Skin
  • The ichthyosis disappears during childhood and mild atrophic, hypopigmented skin lesions persist. Cutaneous adnexa such as hairs and sweat glands in the affected areas can be absent.[ntvg.nl]
Hearing Impairment
  • XERODERMA PIGMENTOSUM, COMPLEMENTATION GROUP F; XPF Is also known as xp6 xp, group f xeroderma pigmentosum vi Related symptoms: Intellectual disability Short stature Hearing impairment Microcephaly Scoliosis SOURCES: MESH OMIM MENDELIAN More info about[mendelian.co]

  • The clinical features in the milder form are nonspecific like mongoloid face, snub nose, slanting of the eyes, short neck and trunk, cataract and mild skeletal deformities. Dwarfism is not severe.[ijri.org]
  • Figure 1 Clinical photo taken at the age of 2 months showed short neck, and predominantly rhizomelic shortening of the upper and lower limbs. Note left femur more severely affected than the right.[hkjpaed.org]
  • Such features have included abnormal calcifications and potential narrowing (stenosis) of the windpipe (trachea) and/or the larynx, which connects the throat and the trachea; an unusually short neck; abnormalities of the nails; various structural malformations[rarediseases.org]
Wide Flat Nose
  • Congenital (sectoral) cataract, midface hypoplasia, wide/flat nose, hypothelorism and structural brain anomalies with mental retardation can be present. Sometimes there is a linear alopecia.[ntvg.nl]
Clitoromegaly
  • Genitourinary lesions commonly present as hydronephrosis, cryptorchidism and clitoromegaly. Hydronephrosis can be diagnosed by renal ultrasound. Urology or gynecology referral should be made if any of these symptoms are found.[dermatologyadvisor.com]

Workup

Dyslipidemia
  • Since isotretinoin is associated with severe systemic side effects, eg, teratogenicity, hepatic dysfunction, dyslipidemia, visual changes, pseudotumor cerebri, etc, the risk/benefit ratio should be carefully weighed before initiating treatment.[dermatologyadvisor.com]

Treatment

  • Treatment progress The treatment was started after achieving the IJ stage, when the patient was 14 years and 10 months old.[cyberleninka.org]
  • Decisions about use of a new treatment, or about a change in your current treatment plan, should be in consultation with your doctor or other healthcare professional.[healthetreatment.com]
  • Management and treatment Management is multidisciplinary. Treatment of skin lesions includes the use of emollients and keratolytics (i.e. ammonium lactate 12%, petrolatum ointment).[orpha.net]
  • Treatment - Conradi-Hunermann syndrome Treatment can involve operations to lengthen the leg bones, which involves many visits to the hospital. Other symptoms can be treated with medicine or surgery.[checkorphan.org]
  • What are the available treatments for Conradi-Hünermann syndrome? Unfortunately, there is no cure for Conradi-Hünermann syndrome as of yet, so treatment is directed towards managing the symptoms of the condition and supporting its’ patients.[patientworthy.com]

  • Incontinentia pigmenti Lab Bone films Neonatal skin biopsy may reveal calcium in the epidermis with von Kossa's stain Peroxisomal function in cultured fibroblasts Management Referral to orthopedist, dermatologist, ophthalmologist Examine first degree relatives Prognosis[cram.com]
  • Prognosis There is usually no effect on life-expectancy (rarely scoliosis can compromise cardiac and pulmonary function) but quality of life may be severely affected.[orpha.net]
  • There are also Standard interventions for congenital heart defects, kidney anomalies, and hearing loss Prognosis Typically life expectancy of female patients is not affected unless severe scoliosis has com promised lung and heart function.[conradihunermannsyndrome.weebly.com]

Etiology

  • A possible role for homeobox-containing genes in the etiology of this type of chondrodysplasia punctata is suggested as an explanation for the coincidence of these two syndromes.[tandfonline.com]
  • They are organised into groups, and further divided into clinical, etiological or histopathological sub-types.[orpha.net]
  • Etiology CDPX2 is caused by mutations in the gene encoding delta8-delta7-sterol isomerase emopamil-binding protein (EBP) at Xp11.23-p11.22.[dermatologyadvisor.com]

Epidemiology

  • Summary Epidemiology Annual incidence has been estimated to be at least 1/400,000 births with 95% of patients being female. Clinical description 'Congenital ichthyosiform erythroderma is the typical neonatal manifestation.[orpha.net]

Pathophysiology

  • Pathophysiology The molecular mechanism by which mutation of EBP gene causes this characteristic syndrome remains unknown.[dermatologyadvisor.com]

Prevention

  • Orthopedic measures, including surgery in severe cases, is recommended to help prevent or correct the skeletal abnormalities that are associated with the disorder (craniofacial malformations, scoliosis, etc.).[patientworthy.com]
  • The children’s physiatrist had prescribed semi-orthopedic anti-varus shoes with correction for her difference in leg length to stimulate her walking independently and prevent further feet deformities.[ntvg.nl]
  • To help, prevent, or correct certain skeletal malformation, orthopedic measures and surgeries are recommended. Also for craniofacial malformations, scoliosis or other physical abnormalities surgery might be advised.[conradihunermannsyndrome.weebly.com]
  • Audience: Paediatricians, neurologists, clinical biochemists, pathologists, genetic counsellors, obstetricians, and GPs interested in the recognition, diagnosis and prenatal prevention of peroxisomal disorders.[books.google.ro]
