Likely inborn error of metabolism v9.10 FOCAD Ida Ertmanska changed review comment from: PMID: 35864190 Traspas et al., 2022
Report of 14 children from ten unrelated families (various ancestries, 6/10 families were consanguineous) presenting with a syndromic form of pediatric liver cirrhosis. WGS/WES detected biallelic FOCAD variants which segregate with disease. FOCAD variants detected: 3 missense, 3 stop-gain, 2 frameshift, 5 splicing, and 1 large deletion. LOF is the mechanism of disease. Absence of FOCAD protein shown in F1 and F2 individuals.

The liver phenotype was marked by cirrhosis (71.4%) with multinodularity (57.1%). Intrahepatic cholestasis was diagnosed in 35.7% of the patients, with associated jaundice (35.7%) and biliary hyperplasia (28.6%). Splenomegaly and hepatomegaly also deteced in 71% of patients. In one case, liver transplant was necessary at 6 months of age. Additional non-liver related phenotypes: abdominal distension (78.6%), diarrhea (57.1%), as well as metabolic anomalies (85.7%), hernias, IUGR. Congenital cardiac and genitourinary anomalies present in 42% of patients. 6 children passed away due to hepatic or multiorgan failure (5 before age 1 year).

Moreover, focad-/- knockout zebrafish phenocopied the human disease, revealing altered mRNA degradation processes in the liver.

Added comment: New gene added by Zornitza Stark (Australian Genomics). This gene is associated with an appropriate phenotype in OMIM but not in Gene2Phenotype. There is enough evidence for this gene to be Green. The gene has been given an Amber rating and will be promoted to Green at the next review.

Review from Zornitza Stark (Australian Genomics) on the Cholestasis panel:
Homozygous and compound heterozygous variants (missense, nonsense and frameshift) found in 8 Japanese patients from unrelated families with unexplained galactosaemia. (No variants in GALT, GALK1, and GALE). In vitro expression analysis and enzyme activity assay of the patients’ peripheral blood mononuclear cells showed total lack of or compromised expression of GALM protein. One homozygote for one of these variants p.(Gly142Arg) in gnomAD (African population). (Wada, Y. et al 2019; PMID: 30451973) Note only two individuals were reported as having transient cholestasis.
