All in all, a detailed risk estimation cannot be given in the present case, but a prenatal diagnosis should be performed in further pregnancies of II.2, as well as of his brother. [jmg.bmj.com]

• Short Stature

  In addition to non-specific mental retardation and short stature, there is, in common, a characteristic facies, including down-turned corners of the mouth, a slightly bulbous nose, moderately large ears, suggestively wide-set eyes with an antimongoloid [ncbi.nlm.nih.gov]

  Characteristic clinical features of partial trisomy 9p are mental retardation of various degree, short stature, craniofacial abnormalities, short fingers, simian crease, and single crease of the fifth finger. [jmg.bmj.com]

  Affected children may be below average height for their age (short stature). In some cases, affected children have been diagnosed with growth hormone deficiency. [rarediseases.org]

• Short Finger

  Characteristic clinical features of partial trisomy 9p are mental retardation of various degree, short stature, craniofacial abnormalities, short fingers, simian crease, and single crease of the fifth finger. [jmg.bmj.com]

  These may include decreased length of specific bones of the fingers and toes (phalanges) and within the hands (metacarpals) and feet (metatarsals); short fingers and toes (digits) with small nails; and/or the pinkies may be fixed or ‘locked’ in a bent [rarediseases.org]

• Failure to Thrive

  Hypotonia can affect infants, most often related to difficulty feeding, resulting in the failure to gain weight and grow at the expected rate (failure to thrive). In general, growth deficiency primarily begins after birth (postnatally). [rarediseases.org]

• Heart Disease

  It is characterized by delayed mental and psychomotor growth, craniofacial dysmorphisms, skeletal alterations, central nervous system abnormalities, congenital heart disease, and, to a lesser extent, kidney disorders. [pubmed.ncbi.nlm.nih.gov]

  In severe cases, congenital heart disease may lead to potentially life-threatening complications. Surgery may be necessary to remedy heart defects along with follow-up care and monitoring. [rarediseases.org]

• Low Set Ears

  The patient showed facial dysmorphisms typical of trisomy 9p syndrome, such as brachycephaly, hypertelorism, down-slanting palpebral fissures, broad prominent nose, and large low-set ears. [ncbi.nlm.nih.gov]

• Strabismus

• Short Arm

  The missing segment is inserted in the short arm of the der(5). [jmg.bmj.com]

  The observed phenotypic findings illustrate the deficiencies associated with a complete duplication of the short arm of chromosome 9 and can aid in the genetic counseling of this particular chromosomal anomaly. [pesquisa.bvsalud.org]

  The clinical features are remarkably similar to those recently recognized and increasingly reported in full short arm (9p) trisomy and should be considered a modification of the same syndrome. [ncbi.nlm.nih.gov]

  In trisomy 9p, the trisomy (or duplicated material) may involve a portion of the short arm (9p), the entire short arm, or the short arm and a portion of the long arm (9q) of chromosome 9. [rarediseases.org]
