Genes affected
GBX1 (HGNC:4185): (gastrulation brain homeobox 1) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of nervous system development and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within adult walking behavior; neuron differentiation; and proprioception. Predicted to be part of chromatin. Predicted to be active in nucleus.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 31, 2023The c.157C>T (p.R53W) alteration is located in exon 1 (coding exon 1) of the GBX1 gene. This alteration results from a C to T substitution at nucleotide position 157, causing the arginine (R) at amino acid position 53 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
