Chromosome 3q22.2‐q26.2 Interstitial Deletion in a Patient With Wisconsin Syndrome, Blepharophimosis‐Ptosis‐Epicanthus Inversus Syndrome, Dandy‐Walker Malformation, Pierre Robin Sequence, and Recurrent Infections

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Wisconsin syndrome is a very rare genetic condition characterized by coarse facies, prominent nasal tip, bushy high arched/upsweeping eyebrows, and a full/everted lower lip. Deletion of chromosome 3q24q25 region is considered critical for its manifestation.

Severe Nerve Enlargement in SOS2‐Related Noonan Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan syndrome is a genetic multisystem congenital disorder, caused by pathogenic variants in genes that encode components of the RAS/MAPK signaling pathway. Pathogenic variants in SOS2 represent less than 2% of cases with NS. The phenotype includes a particularly high prevalence (65%) of lymphatic disease. Recently, severe nerve enlargements

Genotype–Phenotype Correlations, Mortality, and Clinical Insights in Keratitis–Ichthyosis–Deafness Syndrome: A Comprehensive Review and Case Report

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Keratosis–ichthyosis–deafness (KID) syndrome is a rare autosomal dominant ectodermal disease caused by mutations in the GJB2 gene, which encodes the gap junction protein Connexin 26 (Cx26) located on Chr. 13q12.11. This study presents the first mortality analysis associated with KID syndrome, focusing on a case report of a Latin American ...
