Abstract
Esophageal atresia/tracheoesophageal fistula (EA/TEF) is a life-threatening birth defect that often occurs with other major birth defects (EA/TEF+). Despite advances in genetic testing, a molecular diagnosis can only be made in a minority of EA/TEF+ cases. Here, we analyzed clinical exome sequencing data and data from the DECIPHER database to determine the efficacy of exome sequencing in cases of EA/TEF+ and to identify phenotypic expansions involving EA/TEF. Among 67 individuals with EA/TEF+ referred for clinical exome sequencing, a definitive or probable diagnosis was made in 11 cases for an efficacy rate of 16% (11/67). This efficacy rate is significantly lower than that reported for other major birth defects, suggesting that polygenic, multifactorial, epigenetic, and/or environmental factors may play a particularly important role in EA/TEF pathogenesis. Our cohort included individuals with pathogenic or likely pathogenic variants that affect TCF4 and its downstream target NRXN1, and FANCA, FANCB, and FANCC, which are associated with Fanconi anemia. These cases, previously published case reports, and comparisons to other EA/TEF genes made using a machine learning algorithm, provide evidence in support of a potential pathogenic role for these genes in the development of EA/TEF.

J Pediatr Endocrinol Metab 2022; 35:1410-1421. [PMID: 36103668 DOI: 10.1515/jpem-2022-0254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Accepted: 08/29/2022] [Indexed: 11/15/2022]
Abstract
OBJECTIVES Although at least 598 genes are involved in the development of the hypothalamo-pituitary-testicular (HPT) axis, mutations in only 75 genes have so far been shown to cause delayed puberty. METHODS Six male patients with failed puberty, manifested as absence of pubertal changes by 18 years of age, underwent whole exome sequencing of genomic DNA with subsequent bioinformatics analysis and confirmation of selected variants by Sanger sequencing. Genes having plausibly pathogenic non-synonymous variants were characterized as group A (previously reported to cause delayed puberty), group B (expressed in the HPT-axis but no mutations therein were reported to cause delayed puberty) or group C (not reported previously to be connected with HPT-axis). RESULTS We identified variants in genes involved in GnRH neuron differentiation (2 in group A, 1 in group C), GnRH neuron migration (2 each in groups A and C), development of GnRH neural connections with supra-hypothalamic and hypothalamic neurons (2 each in groups A and C), neuron homeostasis (1 in group C), molecules regulating GnRH neuron activity (2 each in groups B and C), receptors/proteins expressed on GnRH neurons (1 in group B), signaling molecules (3 in group C), GnRH synthesis (1 in group B), gonadotropins production and release (1 each in groups A, B, and C) and action of the steroid hormone (1 in group A). CONCLUSIONS Non-synonymous variants were identified in 16 genes of the HPT-axis, which comprised 4 in group A that contains genes previously reported to cause delayed puberty, 4 in group B that are expressed along HPT-axis but no mutations therein were reported previously to cause delayed puberty and 8 in group C that contains novel candidate genes, suggesting wider genetic causes of failed male puberty.
