Presentation
These patients presented with evidence of prenatal overgrowth and developed postnatal overgrowth. [hindawi.com]
In addition, we present data on the extended family. Among patients with epilepsy followed up in our hospital, we identified 2 brothers (Figure 1) with epilepsy and mental retardation who presented dysmorphic features. [jamanetwork.com]
These patients presented tonic-atonic, tonic–clonic, and absence seizures. [elsevier.es]

The present observation emphasises the importance of chromosome analysis in patients with overgrowth and mental retardation. [nature.com]

- Feeding Difficulties
At 8 months old he had occasional feeding difficulties and moderate growth retardation. Short term peripheral blood lymphocyte cultures were initiated and harvested by standard protocols. [jmg.bmj.com]
Such feeding and swallowing difficulties may result in or contribute to an affected infant’s failure to grow or gain weight at the expected rate (failure to thrive). [rarediseases.org]
- Surgical Procedure
The surgical procedures performed will depend upon the severity and location of the anatomical abnormalities and their associated symptoms. [rarediseases.org]
- Short Stature
Dysmorphologic evaluation showed short stature, dysmorphic ears, broad nasal bridge, hypertelorism, long nasolabial philtrum, high arched palate, scoliosis, and short fingers. [jamanetwork.com]
It is tempting to speculate that dosage excess of genes located in 15q24 leads to short limbs/IUGR instead of tall stature. [dovepress.com]

Respiratoric
- Respiratory Distress
The presence of congenital heart disease, skeletal abnormalities, respiratory distress/infection, and seizures varied among patients. Our case is, to our knowledge, the first de novo interstitial tandem duplication of only the medial region of 15q. [jmg.bmj.com]
Gastrointestinal
- Failure to Thrive
The infant suffered from respiratory complications and failure to thrive. Further investigations showed hypothyroidism and a vascular ring (which was subsequently repaired). [jmg.bmj.com]
Case Report An eight-month-old male child born to non-consanguineous parents was referred for genetic analysis with a history of develop-mental delay and failure to thrive. The father was 30 years old and the mother was 28 years old. [indianpediatrics.net]
Finally, patient 3 had IUGR, failure to thrive, mental and psychomotor retard, café-au-lait patches. We reviewed 96 patients with chromosome 15q duplication and we summarized the main clinical features in Table 1. [ec.bioscientifica.com]
Such feeding and swallowing difficulties may result in or contribute to an affected infant’s failure to grow or gain weight at the expected rate (failure to thrive). [rarediseases.org]
Cardiovascular
- Heart Disease
The presence of congenital heart disease, skeletal abnormalities, respiratory distress/infection, and seizures varied among patients. Our case is, to our knowledge, the first de novo interstitial tandem duplication of only the medial region of 15q. [jmg.bmj.com]
Commonly associated defects include seizures and congenital heart disease, a common cause of premature death in these children. [indianpediatrics.net]
Jaw & Teeth
- High Arched Palate
He had facial asymmetry, strabismus involving the left eye, narrow down-slanting palpebral fissures, prominent nose, overhanging columella, long philtrum, small pointed chin, midline crease in the lower lip and high arched palate [Figure 2]. [pediatricneurosciences.com]
On examination, the child had dysmorphic features in the form of hypertelorism, down slanting eyes, low-set large ears, prominent metopic suture, bulbous nose, mandibular hypoplasia and high arched palate (Fig. 1). [indianpediatrics.net]
Cardiomyopathy, renal anomalies or abnormal genitalia may also be found.[6,7] Our patient had microcephaly, micrognathia, long philtrum and high arched palate, which was consistent with the physical appearance described in this anomaly. [ncbi.nlm.nih.gov]

Musculoskeletal
- Long Arm
Each chromosome has a short arm designated as “p” and a long arm identified by the letter “q.” Chromosomes are further subdivided into bands that are numbered. For example, “15q21” refers to band 21 on the long arm of chromosome 15. [rarediseases.org]

On examination, small palpebral fissures and mild micrognathia were present. The fingers were long and slender and there was bilateral fifth finger clinodactyly. There was also incurving and overlapping of the toes. [hindawi.com]
Psychiatrical
- Suggestibility
The previous report of a child with cloverleaf skull and partial duplication of 15q25→qter and the Man-on-Mouse Homology map suggests that a critical segment for synostosis of sutures may be in this region. © 1992 Wiley-Liss, Inc. [onlinelibrary.wiley.com]
Clinical similarities between unrelated individuals with similar duplicated 15q material, but differing second chromosomes, suggest that the phenotype is due to the extra distal 15q chromosomal material. [ncbi.nlm.nih.gov]
A low-resolution cytogenetic evaluation performed at the time of death, 20 years earlier, was considered normal; however, his clinical features suggest that he had a 15q monosomy. Figure 2. [jamanetwork.com]
We suggest that overgrowth might be causally related to a dosage excess of IGF1R gene. [nature.com]
The abnormalities seen in this patient are consistent with previously reported cases of partial trisomy 15q and suggest a clinically recognisable phenotype. [jmg.bmj.com]

In males, such abnormalities may include failure of the testes to descend into the scrotum (cryptorchidism) and/or low levels of testicular function (hypogonadism), resulting in delayed development of secondary sexual characteristics (i.e., deepening [rarediseases.org]
Neurologic
- Seizure
Other types of seizures include partial complex seizures, generalised myoclonic seizures with adult onset, generalised tonic–clonic seizures, and benign epilepsy with centrotemporal spikes. [elsevier.es]
At age 8 years he began to have generalized seizures with poor control despite medication. [jamanetwork.com]
There was no history of seizures, encephalopathy, or jaundice in the neonatal period. He developed social smile at 3 months, and was recognizing his mother and reaching out for objects at the time of presentation. [pediatricneurosciences.com]
Commonly associated defects include seizures and congenital heart disease, a common cause of premature death in these children. [indianpediatrics.net]
Treatment
Treatment may require the coordinated efforts of a team of specialists. [rarediseases.org]
