Genes affected

HOXB1 (HGNC:5111): (homeobox B1) This gene belongs to the homeobox family of genes. The homeobox genes encode a highly conserved family of transcription factors that play an important role in morphogenesis in all multicellular organisms. Mammals possess four similar homeobox gene clusters, HOXA, HOXB, HOXC and HOXD, located on different chromosomes, consisting of 9 to 11 genes arranged in tandem. This gene is one of several homeobox HOXB genes located in a cluster on chromosome 17. [provided by RefSeq, Jul 2008]

The c.607C>G (p.P203A) alteration is located in exon 2 (coding exon 2) of the HOXB1 gene. This alteration results from a C to G substitution at nucleotide position 607, causing the proline (P) at amino acid position 203 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
