Fetal anomalies
Gene: PDHX
The rating of this gene has been updated to Green and the mode of inheritance set to BIALLELIC, autosomal or pseudoautosomal following NHS Genomic Medicine Service approval.Created: 10 Oct 2023, 3:39 p.m. | Last Modified: 10 Oct 2023, 3:39 p.m.

Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
This gene and phenotype were reviewed during a meeting on 2nd March 2023 between representatives of the North Thames and Central & South R21 testing GLHs. Clinical review and curation was performed by Lyn Chitty, (North Thames GLH), and Stephanie Allen, Denise Williams, Anna de Burca and Megan Horton-Bell (Central & South GLH). Outcome of review: Confirmed that the phenotype is fetally relevant, support adding to the Fetal anomalies panel as a Green gene.Created: 5 May 2023, 3 p.m. | Last Modified: 5 May 2023, 3 p.m.

On 14 panels, inc. Fetal anomalies, severe paediatric disorders, IEM, DDG2P. Associated with Lacticacidemia due to PDX1 deficiency (AR). Notes on R21: DDG2P rating in original PAGE list: Confirmed for LACTICACIDEMIA DUE TO PDX1 DEFICIENCY. Outcome of review: Presentation of mitochondrial disorders can be variable, and most aren't obvious at birth. Therefore exclude unless the gene has been directly associated with a fetal presentation.

Barnerias et al., 2010 PMID 20002125: States prenatal brain anomalies were identified in patients, but doesnt detail which anomalies in which patients. Conclusion: weak link to prenatal phenotypes (growth retardation, neurological anomalies. Specifics stated in one patient). ?RelevantCreated: 5 May 2023, 3 p.m. | Last Modified: 5 May 2023, 3 p.m.
