Letters to Editor: The risk for clinically significant copy number variants in pregnancies with two soft markers, Geriatriophobia - a new concept in the medical world in Israel.
The study aimed to characterize perinatal intracranial hemorrhage (pICH), focusing on differences between cases diagnosed before and after birth and analyzing their causes and clinical patterns.
Conducted over a decade, the research included 110 pICH cases, revealing that intraventricular hemorrhage (IVH) was most prevalent, particularly in prenatally diagnosed cases, while subpial hemorrhage was exclusively identified postnatally.
The findings indicated that genetic disorders contributed to nearly a third of pICH cases, highlighting the necessity for next-generation sequencing to better understand genetic factors associated with prenatally diagnosed hemorrhages.
The study examined the occurrence and characteristics of callosal injury in fetuses affected by cytomegalovirus (CMV) fetopathy using a retrospective analysis of patients with confirmed CMV-PCR.
Among 72 patients, 34.7% showed callosal abnormalities, primarily associated with other central nervous system issues like periventricular hyperechogenicity and calcifications.
The findings suggest that callosal injury is a common consequence of CMV infection, indicating a worse prognosis and increased risk of neurodevelopmental impairment, with distinct prenatal patterns of injury compared to what is seen postnatally.
* Trio exome sequencing revealed a likely pathogenic variant in the KIDINS220 gene, which is associated with various neurological and developmental disorders.
* The case highlights a more severe clinical presentation of the KIDINS220 variant, contrasting with previous limited reports primarily focused on cases with ventriculomegaly.
