Genes affected
HOXB13 (HGNC:5112): (homeobox B13) This gene encodes a transcription factor that belongs to the homeobox gene family. Genes of this family are highly conserved among vertebrates and essential for vertebrate embryonic development. This gene has been implicated to play a role in fetal skin development and cutaneous regeneration. In mice, a similar gene was shown to exhibit temporal and spatial colinearity in the main body axis of the embryo, but was not expressed in the secondary axes, which suggests functions in body patterning along the axis. This gene and other HOXB genes form a gene cluster at chromosome the 17q21-22 region. [provided by RefSeq, Jul 2008]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 05, 2023The p.T41M variant (also known as c.122C>T), located in coding exon 1 of the HOXB13 gene, results from a C to T substitution at nucleotide position 122. The threonine at codon 41 is replaced by methionine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
