Combinations of the most common VACTERL-H features. C: cardiac structural anomalies; R: renal malformations; L: upper limb anomalies (radial ray). Solid: patients with gene and phenotype described (n=561); horizontal stripes: patients who had ≥3/8 VACTERL-H features (n=69); white: patients who had only 2/8 VACTERL-H features (n=78). Horizontal axis: combinations; vertical axis: percent of cases with each combination. The frequencies of the combinations in the patients with gene and phenotype described were RL 19.6%, CL 9.6%, CR 9.1%, and CRL 7.7%; whereas in those who met criteria for VACTERL-H the frequencies were 91.3%, 63.8%, 63.8%, 62.3%, respectively. Eighty-two percent of patients who did not met criteria for VACTERL-H (with only 2 features) had the RL (60.3%), CL (12.8%), or CR (9%) combinations.
