Since mutations in these genes and excess Mn potentially disrupt similar cellular processes within the basal ganglia, it is reasonable to hypothesize that the expressed symptoms of Parkinson's disease may overlap with that of manganese (Mn) toxicity. (cdc.gov)
The severity of cardiac disease is much gene, which is located on the Xcchromoc greater than the myopathy [ 4 ]. (who.int)

The IVF/PGT procedure is for couples who wish to prevent the passage of genetic abnormalities to their unborn children and those who want their embryos tested for genetic abnormalities while undergoing IVF. (massgeneral.org)

In this study, we report a case of FCD bearing a heterozygous flame-shift mutation within the phosphoinositide kinase, FYVE finger containing ( PIKFYVE ) gene. (molvis.org)

Haplotype analysis placed the cataract locus to a 5.0 cM region between D19S902 and D19S867, in close proximity to the L-ferritin light chain gene (FTL) on chromosome 19q13.3. (nih.gov)

These include orthopedic, cardiovascular, and endocrine abnormalities. (expresshealthcaremgmt.com)

The Ptch mutant mice provide the first mouse model, to our knowledge, of ultraviolet and ionizing radiation-induced basal cell carcinoma-like tumors, and also demonstrate that Ptch inactivation and hedgehog target gene activation are essential for basal cell carcinoma tumorigenesis. (nature.com)
Of 103 gene mutations that lead to the death of a developing fetus in mice, 68% caused defects in the placenta. (babraham.ac.uk)

Due to genetic and phenotypic heterogeneity, it can be difficult to identify the underlying gene defect from the clinical symptoms. (lu.se)
Cerebellar imaging abnormalities were observed in 73-86% (cohort and in silico respectively) of EOA-genes independently of phenotypic comorbidity. (lu.se)

CONCLUSIONS: The investigated EOA phenotypes revealed predominantly cerebellar abnormalities, with thalamo-cortical abnormalities in the mixed phenotypes, suggesting anatomical network involvement in EOA pathogenesis. (lu.se)

Of note, both expand the genetic abnormalities to include mutations in specific genes (with minor differences between the two highlighted in red in Table 2 beyond karyotyping abnormalities in WHO 2017. (cap.org)
The UBE3A gene plays a regulatory role on the function of specific monoamine transmitters, which are associated with the dynamics of synaptic plasticity. (spandidos-publications.com)
EOA gene subgroups with myoclonus and epilepsy showed specific enrichment for lysosomal and lipid processes. (lu.se)

Symptoms vary among affected family members and between families, suggesting the participation of modifier genes. (jneurosci.org)

However, more subtle and sophisticated techniques, such as voxel-based morphometry studies have allowed researchers to identify bilateral abnormalities in neural volume in areas of the brain associated with motor functions, such as the caudate nucleus, in the affected members of the KE family when compared to the unaffected family members.
