First report of hypoplastic left heart syndrome in 3p- syndrome and review of candidate genes.

Objective: 3p deletion syndrome is a rare monosomal disease that encompasses deletions throughout the short arm of chromosome 3. It is often in the distal region (3p25-pter), but variations in breakpoints and a complex clinical manifestation exist, with congenital heart defects being considered rare. We present the first case of hypoplastic left heart syndrome and minor dysmorphic features associated with 3p- syndrome.

Exploring the Activation of Atomically Precise [Pt(CO)(PPh)] Clusters: Mechanism and Energetics in Gas Phase and on an Inert Surface.

Atomically precise clusters such as [Pt(CO)(PPh)] ( = 1,2) (PPh is triphenylphosphine) are known as precursors for making oxidation catalysts. However, the changes occurring to the cluster upon thermal activation during the formation of the active catalyst are poorly understood. We have used a combination of hybrid mass spectrometry and surface science to map the thermal decomposition of [Pt(CO)(PPh)](NO).

What Can Really Be Considered a Syndrome? An Insight Based on 16p11.2 Microduplication.

What is the definition of Syndrome? Since the beginning of studies in genetics, certain terminologies have been created and used to define groups of diseases or alterations. With the advancement of knowledge and the emergence of new technologies, the use of basic concepts is being done in a mistaken or often confusing way. Because of this, revisiting and readjusting the old terms becomes imminent.

Turner syndrome and neuropsychological abnormalities: a review and case series.

Objective: The objective of this study was to establish the genotype-phenotype correlation between karyotype results and the neurological and psychiatric alterations presented in patients with Turner syndrome (TS).

Methods: A retrospective study was conducted on the medical records of 10/140 patients with TS and neurophysiological abnormalities seen at a university hospital in southern Brazil. In addition, a literature review spanning the period from January 1, 2012 to January 1, 2023 was carried out using the PubMed and Virtual Health Library databases.

invdup(8)(8q24.13q24.3)-A Complex Alteration and Its Clinical Consequences.

Structural variation is a source of genetic variation that, in some cases, may trigger pathogenicity. Here, we describe two cases, a mother and son, with the same partial inverted duplication of the long arm of chromosome 8 [invdup(8)(q24.21q24.
