Purpose: Glutaric Acid Type I (GA-I) is an inherited metabolic disorder. Although the treatment guidelines for GA-I were established a decade ago, they cannot block the vertical heredity. We aim to apply genetic methods to block the inheritance of GA-I and verifies the efficiency of Next-Generation Sequencing (NGS)-based Preimplantation Genetic Testing for Monogenic disease (PGT-M) of GA-I.Materials and methods: A non-consanguineous Chinese family was diagnosed with GA-I by Sanger sequencing. PGT-M and prenatal diagnosis (PND) were performed for the carrier. 5 blastocysts were used for the trophectoderm biopsy. After Whole-Genome Amplification (WGA), the WGA products were used for Sanger sequencing, NGS-based PGT-M and PGT-A. Sanger sequencing-based PND was performed in second trimester to confirm the results of PGT-M.Results: A compound heterozygous mutation was diagnosed in the GCDH gene with co-segregation. One is [c.533G>A (p.G178E)] and another is [c.914C>T (p.S305L)]. 2 blastocysts were diagnosed as normal and one of them was transferred into the mother’s uterus. Finally, a healthy female was born 39 weeks after transplantation.Conclusion: Our study successfully applied NGS-based PGT-M to avoid GA-I and highlights the efficiency of genetic diagnoses. It has significant implications on genetic counseling and genetic diagnosis for GA-I.

Background: FERM domain-containing protein 4A (FRMD4A) is a scaffolding protein previously proposed to be critical in the regulation of cell polarity in neurons and implicated in human intellectual development.Case Presentation: We report a case of a 3-year-old boy with corpus callosum anomaly, relative macrocephaly, ataxia, and unexplained global developmental delay. Here, compound heterozygous missense mutations in the FRMD4A gene [c.1830G>A, p.(Met610Ile) and c.2973G>C, p.(Gln991His)] were identified in the proband, and subsequent familial segregation showed that each parent had transmitted a mutation.Conclusions: Our results have confirmed the associations of mutations in the FRMD4A gene with intellectual development and indicated that for patients with unexplained global developmental delay, the FRMD4A gene should be included in the analysis of whole exome sequencing data, which can contribute to the identification of more patients affected by this severe phenotypic spectrum.
