No, that's congenital.
The gene for Btk (Bruton's tyrosine kinase) is located on the X chromosome at position Xq21.32. Mutations in the Btk gene can lead to X-linked agammaglobulinemia, a primary immunodeficiency disorder.
The condition is called polydactyly. It is a congenital anomaly where a person is born with more than the usual number of fingers or toes on one or both hands or feet.

X-linked agammaglobulinemia
Agammaglobulinemia is a condition in which gammaglobulins are absent from the blood, or only exist in low concentrations.
