Congenital Heart Defect v0.239 KYNU Chloe Stutterd gene: KYNU was added
gene: KYNU was added to Congenital Heart Defect. Sources: Literature,Expert list
Mode of inheritance for gene: KYNU was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: KYNU were set to 28792876; 33942433
Phenotypes for gene: KYNU were set to MIM# 617661 Vertebral, cardiac, renal, and limb defects syndrome 2
Review for gene: KYNU was set to GREEN
gene: KYNU was marked as current diagnostic
Added comment: Biallelic, inactivating variants in three genes encoding enzymes of the NAD biosynthesis pathway (KYNU, HAAO, and NADSYN1) disrupt NAD synthesis and have been identified in patients with multiple malformations of the heart, kidney, vertebrae, and limbs; these patients have Congenital NAD Deficiency Disorder (PMID: 33942433)

Congenital Heart Defect v0.239 HAAO Chloe Stutterd gene: HAAO was added
gene: HAAO was added to Congenital Heart Defect. Sources: Literature,Expert list
Mode of inheritance for gene: HAAO was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: HAAO were set to 28792876; 33942433
Phenotypes for gene: HAAO were set to Atrial septal defect; Hypoplastic left heart syndrome; Aortic stenosis; Mitral stenosis; Tetralogy of fallot with complete atriventricular canal and pulmonary stenosis; Lsvc and left pulmonary artery arising from the ductus arteriosus; Shone syndrome with aortic coarctation
Review for gene: HAAO was set to GREEN
gene: HAAO was marked as current diagnostic
Added comment: MIM#617660 phenotype is called 'Vertebral, cardiac, renal, and limb defects syndrome type 1' and is a form of Congenital NAD Deficiency Disorder.
