Mendeliome v1.489 PIGN Zornitza Stark edited their review of gene: PIGN: Added comment: Large cohort study of 21 new and review of 40 previously published cases in PMID 36322149

Biallelic-truncating variants were detected in 16 patients-10 with Fryns syndrome, 1 with MCAHS1, 2 with Fryns syndrome/MCAHS1, and 3 with neurologic phenotype. There was an increased risk of prenatal or neonatal death within this group (6 deaths were in utero or within 2 months of life; 6 pregnancies were terminated). Incidence of polyhydramnios, congenital anomalies (eg, diaphragmatic hernia), and dysmorphism was significantly increased. Biallelic missense or mixed genotype were reported in the remaining 45 cases-32 showed a neurologic phenotype and 12 had MCAHS1. No cases of diaphragmatic hernia or abdominal wall defects were seen in this group except patient 1 in which we found the missense variant p.Ser893Arg to result in functionally null alleles, suggesting the possibility of an undescribed functionally important region in the final exon.; Changed publications: 36322149; Changed phenotypes: Multiple congenital anomalies-hypotonia-seizures syndrome 1, MIM# 614080, MONDO:0013563, Fryns syndrome
