Syndromic Congenital Heart Disease in a Child with 6q24.3-q25.1 Microdeletion: A Case Report with Genotype–Phenotype Correlation

Chromosome 6q24.3-q25.1 microdeletion syndrome is a rare contiguous gene deletion disorder associated with multilevel congenital heart defects, growth abnormalities, and dysmorphic features. We report the case of an 8-month-old female child who presented with fever, cough, and respiratory distress. She had a history of...

STANKIEWICZ–ISIDOR SYNDROME CAUSED BY A MICRODELETION OF THE LONG ARM OF CHROMOSOME 17: A CASE REPORT AND LITERATURE REVIEW

Stankiewicz–Isidor syndrome (STISS; OMIM #617516) is a rare autosomal dominant disorder caused by haploinsufficiency of the PSMD12 gene. Most reported cases are associated with point variants in the PSMD12 gene, whereas microdeletions involving this locus are much rarer. We present a clinical case of an 8-month-old gir...

Infantile 22q11.2 deletion syndrome with secondary monogenic variants following inconclusive whole exome sequencing: a case report

This case highlights the classic expanded phenotype of 22q11.2DS in infancy and demonstrates the technical limitations of WES in identifying microdeletions, and illustrates how parental consanguinity can introduce overlapping or incidental genetic findings (TTN, NEXN, ANO5) that require careful clinical correlation.

Familial Isolated Tetralogy of Fallot Associated With JAG1 Variant: Justifying Phenotype-Agnostic Genetic Workup for Critical Congenital Heart Disease.

This case report of a female neonate that presented at birth to the cardiothoracic intensive care unit with critical congenital heart disease (CHD), specifically, Tetralogy of Fallot (ToF), underscores the potential importance of phenotype-agnostic genetic workup for critical CHD in the neonatal setting.
