Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 10, 2024The c.788G>A (p.R263Q) alteration is located in exon 2 (coding exon 2) of the GBX1 gene. This alteration results from a G to A substitution at nucleotide position 788, causing the arginine (R) at amino acid position 263 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
