Disease Associations Clubfoot, congenital, with or without deficiency of long bones and/or mirror-image polydactyly (CCF) [MIM:119800]: A congenital limb deformity defined as fixation of the foot in cavus, adductus, varus, and equinus (i.e., inclined inwards, axially rotated outwards, and pointing downwards) with concomitant soft tissue abnormalities. Clubfoot may occur in isolation or as part of a syndrome. Some patients present tibial hemimelia, bilateral patellar hypoplasia, and preaxial mirror-image polydactyly. {ECO:0000269PubMed:18950742, ECO:0000269PubMed:22258522}. Note=The disease is caused by mutations affecting the gene represented in this entry.Liebenberg syndrome (LBNBG) [MIM:186550]: An upper limb- malformation syndrome characterized by the combination of dysplastic elbow joints and the fusion of wrist bones with consequent radial deviation. {ECO:0000269PubMed:23022097}. Note=The gene represented in this entry is involved in disease pathogenesis. A chromosomal aberration involving the PITX1 locus results in LBNBG. Translocation t(5;18)(q31.1;q12.3). Additionally, two chromosome 5 deletions located 5'of PITX1 have been found in LBNBG patients. These structural variations cause altered expression of PITX1 in the forelimb via the activation of ectopic enhancers (PubMed:23022097). {ECO:0000269PubMed:23022097}.
