Obstetric History

Isovaleric acidemia is an inborn error of metabolism, inherited as an autosomal recessive disorder, caused by deficiency of isovaleryl- Coenzyme A (CoA) dehydrogenase, leading to elevated plasma isovaleric acid and urine isovalerylglycine levels. Isovaleric acidemia is an unusual disorder with an incidence of 1:67,000 in India. Parents of the child are assumed to be carriers and the offsprings have a one in four (25%) chance of inheriting the disorder. The present article reports a 33-year-old, Gravida 3 Para 2 Live 0 (G3P2L0) at 38 week + 1 day, with previous two Lower Segment Caesarean Surgery (LSCS) and two neonatal deaths, who delivered a term boy baby with incidental finding of isovaleric acidemia at birth. Isovaleric acidemia could sometimes be a rare case for bad obstetric history and should be considered while evaluating a patient. Also, it is now possible to diagnose the condition by early prenatal tests and even before pregnancy by Preimplantation Genetic Diagnosis (PIGD) and by taking necessary steps.

Abstract Objective To evaluate the cause of short stature in children. Case presentation Two children with suspected skeletal dysplasia and short stature were evaluated. Conclusions The 3-M syndrome is a primordial growth disorder manifesting severe postnatal growth restriction, skeletal anomalies and prominent fleshy heels. The 3-M syndrome is a genetically heterogeneous disorder and the phenotype is similar. This is a rare autosomal recessive disorder with normal intellect. Two affected children have been identified by whole-exome sequencing. One patient harboured a compound heterozygous variant and the other was a homozygous missense variant. The genetic diagnosis helped in counselling the families and facilitated prenatal diagnosis in one (case 1) family.

Background: Antenatal Bartter syndrome is an autosomal recessive disorder causing severe polyuria that leads to severe polyhydramnios and preterm labor. Prenatal diagnosis of antenatal Bartter syndrome is difficult because the genetic diagnosis can only be confirmed following a clinical diagnosis in infants. Reports of prenatal diagnosis and treatment of antenatal Bartter syndrome are limited. Case Presentation: We present the case of a 33-year-old pregnant woman with refractory polyhydramnios at 31 weeks of gestation. There were no structural anomalies or placental problems on ultrasonography; therefore, antenatal Bartter syndrome was suspected. With repeated amniocentesis and indomethacin therapy, the pregnancy continued to 36 weeks of gestation. The clinical features of the infant and subsequent genetic testing confirmed the diagnosis of antenatal Bartter syndrome. The baby was in good clinical condition at the 3-month follow-up visit. Conclusions: For pregnant women with early onset and refractory severe polyhydramnios without morphological anomalies, antenatal Bartter syndrome should be highly suspected.

Spinal muscular atrophy (SMA) is a severe neurodegenerative autosomal recessive disorder. Most of patients are caused by the homozygous absence of exon 7 of the telomeric copy of the SMN gene (SMNt) on chromosome. Children with SMA often died prematurely at school age. Therefore, the aim of the study was to improve protocol for spinal muscular atrophy preimplantation genetic diagnosis by using the minisequencing technique. The study was conducted on 30 embryonic cell templates byopsied plus embryos, and four couples were treated using this method. Five unaffected embryos were transferred which resulted in two clinical pregnancy. We have successfully applied the technique of minisequencing for the Preimplantation Genetic Diagnosis of spinal muscular atrophy.

Branched Chain

Isovaleric acidemia, an autosomal recessive disorder, is due to isovaleryl-coenzyme A dehydrogenase deficiency and is one of the branched-chain aminoacidopathies. Isovaleric acidemia may present in the neonatal period with an acute episode of severe metabolic acidosis, ketosis, and vomiting and may lead to coma and death in the first 2 months of life. This report concerns an infant who presented at 10 days of age because of lethargy, poor feeding, hypothermia, cholestasis, and thrombocytopenia, leukopenia, and profound pancytopenia. Death occurred at 19 days of age. Autopsy showed mild fatty change in the liver and extramedullary hematopoiesis, generalized Escherichia coli sepsis, and myelodysplasia of the bone marrow with arrest of the myeloid series at the promyelocytic stage. The appearance resembled promyelocytic leukemia, but the diagnostic 15:17 translocation was not present. The maturation arrest in granulopoiesis in isovaleric acidemia appears to be most likely due to a direct metabolic effect on granulocyte precursor cells.

AbstractSpondylo-ocular syndrome (SOS) is a rare autosomal recessive disorder and affects primarily ocular and spinal tissues. This case report presents an Omani child with a novel homozygous variant, c.2070 G > A (p.Trp690Ter) in XYLT2 associated with SOS for the first time. Oman and other Middle East countries have a high consanguine marriage rate. Our case report will increase knowledge of SOS syndrome to be able to provide genetic diagnosis and counseling for other family members and families as well as prenatal diagnostics for the future pregnancies.

Abstract Objectives Phenylketonuria (PKU) is an inherited autosomal recessive disorder of phenylalanine metabolism. It is mainly caused by a deficiency in phenylalanine hydroxylase (PAH) and frequently diagnosed with Sanger sequencing. To some extent, allelic dropout can explain the inconsistency in genotype and phenotype. Methods Three families were evaluated through DNA sequence analysis, multiplex ligation-dependent probe amplification (MLPA) and prenatal diagnosis technologies. The possibility of inconsistency in phenotype and genotype with c.331C>T variant was analysed. Results Through pedigree analysis, three mothers carried a homozygous c.331C>T variant, which was a false-positive result. New primers were used, and this error was caused by allelic dropout. In this case, c.158G>A was likely a benign variant. Conclusions Sequence variants in primer-binding regions could cause allelic dropout, creating unpredictable errors in genotyping. Our results emphasised the need for careful measures to treat genotype–phenotype inconsistencies.

AbstractJoubert syndrome (JS) is a rare congenital, autosomal recessive disorder characterized by a distinctive brain malformation, developmental delay, ocular motor apraxia, breathing abnormalities, and high clinical and genetic heterogeneity. We are reporting three siblings with JS from consanguineous parents in Syria. Two of them had the same homozygous c.2172delA (p.Trp725Glyfs*) AHI1 mutation and the third was diagnosed prenatally with magnetic resonance imaging. This pathogenic variant is very rare and described in only a few cases in the literature. Multinational collaboration could be of benefit for the patients from undeveloped, low-income countries that have a low-quality health care system, especially for the diagnosis of rare diseases.

Hypernatremic Dehydration

AbstractCongenital glucose-galactose malabsorption (CGGM) is an autosomal recessive disorder originating from an abnormal transporter mechanism in the intestines. It was sourced from a mutation in the SLC5A1 gene, which encodes a sodium-dependent glucose transporter. Here we report a 2-day-old girl with CGGM who presented with severe hypernatremic dehydration due to diarrhea beginning in the first hours of life. Mutation analysis revealed a novel homozygous mutation NM_000343.3 c.127G > A (p.Gly43Arg) in the SLC5A1 gene. Since CGGM can cause fatal diarrhea in the early neonatal period, timely diagnosis of the disease seems to be essential.

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder associated with rapidly progressing periodontitis leading to premature loss of deciduous and permanent dentition and diffuse palmoplantar keratosis. Immunologic alterations, genetic mutations, and role of bacteria are some aetiologic factors. Patients present with early periodontal destruction, so periodontists play a significant role in diagnosis and management. This paper reports a case of Papillon- Lefevre syndrome with its clinical manifestations and challenges for periodontal management which was diagnosed in dental department.

Haim-Munk syndrome is an extremely rare autosomal recessive disorder characterized clinically by palmoplantar hyperkeratosis, aggressive periodontitis with severe alveolar bone destruction, onychogryphosis, pes planus, arachnodactyly, and acro-osteolysis. Consanguinity seems a notable prerequisite. The aim of this study was therefore to report one case of this syndrome and to focus on the periodontal manifestations, in order to attract the attention of dental clinicians to this rare anomaly.
