Presentation
The phenotypic features present in the patient are partially compatible with the reported partial trisomy 15 cases, but also contain some differences. [brieflands.com]
In one patient, macrocephaly is present without overgrowth.18 Craniosynostosis was associated in 3 out of 10 cases. [nature.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]
A child with trisomy 15q syndrome presented prior to the second decade of life with visible disc drusen. The genetic defect may yield a clue to the location of the genetic locus for development of optic disc drusen. [jaapos.org]
Entire Body System
- Multiple Congenital Anomalies
The patient, a 16-month-old boy, was reffered for an evaluation of multiple congenital anomalies. He was born at term by normal delivery to a 23 year-old mother and an unrelated 27 year-old father. [bib.irb.hr]
In conclusion, it is important to take family history and make appropriate diagnostic tests in a child with multiple congenital anomalies, so that detailed genetic counseling can be given to the family. References 1. Hassold TJ, Jacobs PA. [brieflands.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]
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]

Musculoskeletal
- Brachydactyly
It causes the temtamy preaxial brachydactyly syndrome (73). [ec.bioscientifica.com]
Temtamy preaxial brachydactyly syndrome is caused by loss-of-function mutations in chondroitin synthase 1 a potential target of BMP signaling. [ncbi.nlm.nih.gov]

Psychiatrical
- Suggestibility
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]
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]
We suggest that these common clinical features might be due both to the over and down expression of genes mapped on the chromosome 15q26.3. [ec.bioscientifica.com]
The findings suggested chromosomal anomaly and amniocentesis was done for fluorescent in-situ hybridization for chromosome 21 and karyotype analysis. The fluorescent in-situ hybridization for chromosome 21 showed two signals in each cell. [pediatricneurosciences.com]
