Green List (high evidence)

The rating of this gene has been updated to green and the mode of inheritance set to X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males) following NHS Genomic Medicine Service approval.

Panel Version: 4.192
This gene and phenotype were reviewed during meetings between November 2023 & July 2024. The meetings included representatives of the North Thames and Central & South R21 testing GLHs and from the R21 Clinical Oversight Group. Clinical review and curation was performed by Natalie Chandler, Alison Male and Lyn Chitty (North Thames GLH), Stephanie Allen, Natalie Bibb, Esther Kinning and Denise Williams (Central & South GLH) and Natalie Canham, Anna De Burca and Samantha Doyle R21 Clinical Oversight Group. Outcome of review: Confirmed that the phenotype is fetally relevant, support adding to the Fetal anomalies panel as a Green gene.

This review was provided by Alison Male from North Thames GLH: Green in lots of panels. PMID: 16795136 - 33 weeks polyhydramnios & hydrops (scalp edema, pleural effusion & ascites. Another publication describes a case in which an ultrasonography in the third trimester of pregnancy revealed polyhydramnios, bilateral hydronephrosis, hyperechogenic gut, and ascites; post-natal investigation concluded that he had inflammatory involvement of the gastrointestinal and urinary tracts (64). An older brother, also affected by X-linked CGD, presented with severe feeding issues and failure to thrive. Biopsies of esophagus and stomach performed at 6-months-old revealed eosinophilic infiltration of the mucosa and submucosa. Therefore, in this latter family, severe early-onset CGD inflammatory manifestations were observedin utero in the second siblingwho might have had antenatal obstructive lesion of gut and bladder.
