CAKUT v1.69 CTU2 Rebecca Foulger Classified gene: CTU2 as Green List (high evidence)
CAKUT v1.69 CTU2 Rebecca Foulger Added comment: Comment on list classification: Added to panel and rated Green by Zornitza Stark. The Saudi cases all share a founder variant (PMIDs:26633546, 27480277) but a more recent study by the same authors (PMID:31301155) identifies a further 4 patients with a renal phenotype as part of DREAM‐PL syndrome, and new homozygous CTU2 variants. Therefore relevant renal phenotype and sufficient unrelated cases to support association.
CAKUT v1.69 CTU2 Rebecca Foulger Gene: ctu2 has been classified as Green List (High Evidence).
CAKUT v1.68 CTU2 Rebecca Foulger Phenotypes for gene: CTU2 were changed from Microcephaly, facial dysmorphism, renal agenesis, and ambiguous genitalia syndrome, MIM#618142 to DREAM‐PL syndrome; Microcephaly, facial dysmorphism, renal agenesis, and ambiguous genitalia syndrome, 618142
CAKUT v1.67 CTU2 Rebecca Foulger commented on gene: CTU2: PMID:31301155 (Shaheen et al., 2019) show that biallelic CTU2 variants cause DREAM-PL syndrome (dysmorphic facies, renal agenesis, ambiguous genitalia, microcephaly, polydactyly, and lissencephaly) in a further 5 patients. 4/5 patients had a renal phenotype. These 5 patients had different variants to the previously described founder variant, including Ala403Cysfs*23, Leu63Pro, p.Ile505Argfs*41.
CAKUT v1.67 CTU2 Rebecca Foulger commented on gene: CTU2: PMID:27480277 (Shaheen et al., 2016) identified 2 male cousins from the United Arab Emirates with the same founder T247T variant. This founder variant has a frequency of 1/769 in Saudi Arabia.
