Compound heterozygous mutation of SLC25A1 gene in glutaric aciduria type 2

Background: Sudden unexplained postnatal collapse (SUPC) is a condition in which a newborn born at term or near term, and an Apgar score >8 at 5 min and deemed healthy, presents with sudden unexpected cardiorespiratory collapse within the 1st week of life. This can be due to multiple, heterogeneous causes. Clinical Description: A term male neonate developed lethargy and refusal to feed at 56 h of life. The baby was cyanosed, apneic, in peripheral circulatory failure and normothermic. Supportive management was started. Sepsis and congenital heart disease were ruled out. The presence of hypoglycemia, metabolic acidosis and hyperammonemia prompted us to think of a metabolic disorder. Metabolic profile was suggestive of glutaric acuduria (GA). Exome sequencing showed heterozygous missense variants in in exon 7 and 8 of SLC25A1 gene indicative of GA II but reported as of uncertain significance. Both parents were carriers. Management: The final diagnosis was neonatal onset GA II without congenital anomalies. He was started on riboflavin and carnitine. Mechanical ventilation and inotropes were gradually withdrawn and breastfeeding started. Genetic counseling was done. The baby was doing well at the 4-month follow-up visit. Conclusions: Identifying and managing a newborn with SUPC is critical for the outcome. An individualized and rational approach should be used to identify the cause. The management of GA II is primarily supportive with tiding over of metabolic crises and dietary modifications

Desaturation during feeding in a term neonate due to 20p duplication syndrome

Background: Feeding problems are common in preterm neonates of which desaturation during direct feeding is a known entity. However, term newborns have acceptable range of fall in saturation while feeding directly. Here, we report a term newborn with dysmorphic features had desaturation during feeding. Clinical Description: A male baby born to second-degree consanguineous parents at term who was managed for transient tachypnea of newborn had fall in saturation beyond acceptable range during feeding. He had low set ears, high-arched palate, thin upper lip, clinodactyly, and anal tag. Management: The baby was subjected for thorough exploration of respiratory/gastrointestinal/neurological systems which did not reveal attributable findings. Clinical exome sequencing revealed 20p duplication. He was started on orogastric feeding and could be gradually changed to direct feeding at 4 months of age. Conclusions: This report may improve the understanding toward approach to feeding problems in term neonates and also about phenotypic features of 20 p duplication which is less reported

Factor XIII deficiency in a mother-baby dyad

Background: Factor XIII deficiency is a rare autosomal recessive coagulation disorder with varied presentations including prolonged bleeding from the umbilical cord stump, defective wound healing, recurrent miscarriages, or life-threatening intracranial hemorrhage. Clinical Description: A male baby was born at term gestation to a fourth gravida mother with a history of two abortions in the past. He was born out of a third-degree consanguineous marriage, with smooth perinatal transition, but developed multiple episodes of seizures associated with poor feeding and lethargy after 24 h of life. Management: On evaluation, septic screen, metabolic screen (serum electrolytes, calcium, and blood sugar), and coagulation assays were normal. Ultrasonogram revealed a hyperechoic lesion restricted to the left cerebral hemisphere, suggestive of an intraparenchymal hemorrhage. Magnetic resonance imaging brain showed left intraparenchymal hemorrhage with significant mass effect and midline shift. In view of intracranial bleed with normal coagulation assay and other causes being ruled out, factor XIII clot solubility assay was sent and found to have undetectable levels. Factor XIII levels of the mother were also found low (5.5%) though the levels in the father were normal. The baby was managed conservatively with supportive measures in the form of anticonvulsant and anti-edema measures. He recovered successfully and is under close follow-up. Conclusion: A high index of suspicion of factor XIII deficiency should be kept in any neonate presenting with intraparenchymal hemorrhage and recurrent abortions in the mother. This case is being reported to highlight factor XIII deficiency in recurrent pregnancy loss and neonatal intracranial bleeding. Prenatal screening for factor XIII deficiency in these circumstances will help in effective management of future pregnancies

Rhizomelic chondrodysplasia punctata: A missed opportunity for early diagnosis

A male neonate was born with rhizomelic shortening of limbs. Skeletal radiograph showed punctate calcification of epiphysis of humerus, femur, and tibia. The diagnosis and a brief review of literature pertaining to the condition with emphasis on antenatal diagnosis and counseling are being reported
