Genes affected
HOXD1 (HGNC:5132): (homeobox D1) This gene is a member of the Antp homeobox family and encodes a protein with a homeobox DNA-binding domain. This nuclear protein functions as a sequence-specific transcription factor that is involved in differentiation and limb development. Mutations in this gene have been associated with severe developmental defects on the anterior-posterior (a-p) limb axis. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.670G>T (p.G224W) alteration is located in exon 2 (coding exon 2) of the HOXD1 gene. This alteration results from a G to T substitution at nucleotide position 670, causing the glycine (G) at amino acid position 224 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
