Summaries for PITX1 Gene

Entrez Gene Summary for PITX1 Gene

  • This gene encodes a member of the RIEG/PITX homeobox family, which is in the bicoid class of homeodomain proteins. Members of this family are involved in organ development and left-right asymmetry. This protein acts as a transcriptional regulator involved in basal and hormone-regulated activity of prolactin. [provided by RefSeq, Jul 2008]

GeneCards Summary for PITX1 Gene

PITX1 (Paired Like Homeodomain 1) is a Protein Coding gene. Diseases associated with PITX1 include Clubfoot, Congenital, With Or Without Deficiency Of Long Bones And/Or Mirror-Image Polydactyly and Liebenberg Syndrome. Among its related pathways are DAG and IP3 signaling. GO annotations related to this gene include transcription factor activity, sequence-specific DNA binding and transcriptional activator activity, RNA polymerase II core promoter proximal region sequence-specific binding. An important paralog of this gene is PITX3.

UniProtKB/Swiss-Prot for PITX1 Gene

  • May play a role in the development of anterior structures, and in particular, the brain and facies and in specifying the identity or structure of hindlimb.

PITX1_HUMAN
  • 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:0000269 PubMed:18950742, ECO:0000269 PubMed: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:0000269 PubMed: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 5of 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:0000269 PubMed:23022097}.
