PMID: 33276377 - Martin et al 2020 - report 13 affected individuals from 7 unrelated families identified through various different cohort analysis (vertebral malformation, renal hypodysplasia, syndromic esophageal atresia, multiple congenital anomalies) in whom a WBP11 heterozygous variant is considered the top causative candidate. 5 identified variants were predicted to be protein truncating whilst the 6th was a missense variant. All variants are absent from population databases. In family 1, the variant was inherited from the apparently unaffected mother, indicating reduced penetrance, and phenotypic variance within families was observed. Phenotypes covered cardiac, vertebral, renal, craniofacial and gastrointestinal systems. At least at least 5 of the patients affected had features in three component organs so can be considered a VACTERL association. Wbp11 heterozygous null mice had vertebral and renal anomalies.
Vertebral anomalies were noted in 6/13 patients from 5 families. One patient had congenital scoliosis and one abnormalities of the right upper ribs. Genomics England clinical team suggest it just meets the threshold for the skeletal dysplasia panel.
