Genes affected
HOXA3 (HGNC:5104): (homeobox A3) In vertebrates, the genes encoding the class of transcription factors called homeobox genes are found in clusters named A, B, C, and D on four separate chromosomes. Expression of these proteins is spatially and temporally regulated during embryonic development. This gene is part of the A cluster on chromosome 7 and encodes a DNA-binding transcription factor which may regulate gene expression, morphogenesis, and differentiation. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
HOXA-AS2 (HGNC:43745): (HOXA cluster antisense RNA 2) This gene produces a long non-coding RNA that promotes cell proliferation. This transcript may interact with enhancer of zeste homolog 2 Polycomb repressive complex to repress gene expression. [provided by RefSeq, Dec 2017]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 30, 2023The c.1243G>A (p.G415R) alteration is located in exon 4 (coding exon 2) of the HOXA3 gene. This alteration results from a G to A substitution at nucleotide position 1243, causing the glycine (G) at amino acid position 415 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
