Genes affected

HOXB5 (HGNC:5116): (homeobox B5) This gene is a member of the Antp homeobox family and encodes a nuclear protein with a homeobox DNA-binding domain. It is included in a cluster of homeobox B genes located on chromosome 17. The encoded protein functions as a sequence-specific transcription factor that is involved in lung and gut development. Increased expression of this gene is associated with a distinct biologic subset of acute myeloid leukemia (AML) and the occurrence of bronchopulmonary sequestration (BPS) and congenital cystic adenomatoid malformation (CCAM) tissue.

The c.355G>T (p.D119Y) alteration is located in exon 1 (coding exon 1) of the HOXB5 gene. This alteration results from a G to T substitution at nucleotide position 355, causing the aspartic acid (D) at amino acid position 119 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
