Presentation
In the present study, we conducted a variation analysis of the DPP6 gene in patients with autosomal dominant microcephaly and variable mental retardation. [ncbi.nlm.nih.gov]

Although microcephaly and slight mental retardation were present in all subjects but one and short stature was present in four of six affected subjects, the ocular alterations were present in only two subjects. [healio.com]
Our patient, similar to those described by Schmidt et al. 3 and Abdel-Salam et al., 5 also presented postnatal growth retardation, severe mental retardation and cerebral palsy. [scielo.br]
Methods : Two siblings presented with microcephaly, mental retardation, and variable retinal and choroidal abnormalities. Their complete medical and ophthalmologic records were reviewed. Dilated fundus examination and photography was performed. [iovs.arvojournals.org]

Affected individuals may have distinctive facial features, which can include a beaked nose, an abnormally long groove that runs from the base of the nose to the upper lip (philtrum), a high forehead, and large ears. [rarediseases.org]

Excitement
DPP6 appears to play a major role in the regulation of proliferation and migration of neurons in neurogenesis, most likely by participating in neuronal electrical excitability, synaptic integration, and plasticity. [ncbi.nlm.nih.gov]
Workup
For developmental delay, she has been evaluated by the Pediatric Neurology and Medical Genetics units and her workup is as follows: Tandem Mass Spectrometry (TMS), urine Gas Chromatography–Mass Spectrometry (GC-MS), Microarray Comparative Genomic Hybridization [degruyter.com]

The prognosis of microcephaly deepens on the etiology, the size of the head and the associated anomalies. [news-medical.net]
The long-term prognosis and recurrence risk for microcephaly is related to its underlying cause. Microcephaly is characterized by a smaller-than-normal head circumference ( Figures 20-1 and 20-2 ). [mhmedical.com]
Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis. [rarediseases.org]
In general, life expectancy for individuals with microcephaly is reduced and the prognosis for normal brain function is poor. [blueprintgenetics.com]
Etiology
Possible modes of inheritance include autosomal dominant inheritance with variable expressivity, X-linked recessive inheritance with partial expression in the mother, or autosomal recessive inheritance that is etiologically unrelated to the mother’s microcephaly [indiana.pure.elsevier.com]
The etiology for this infant’s microcephaly, which was detected prenatally, is unknown ( Courtesy of John Foster .) [mhmedical.com]
They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]
Devriendt Abstract: Background Autosomal dominant non‐syndromic microcephaly is a rare and heterogenous condition of unknown genetic etiology. [dss.uniroma1.it]
BCD syndrome consists of autosomal dominant abnormalities of the eyelid, lip, and teeth, and the etiology remains unknown. [research.ed.ac.uk]
