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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.937C>A (p.P313T) alteration is located in exon 4 (coding exon 2) of the HOXA3 gene. This alteration results from a C to A substitution at nucleotide position 937, causing the proline (P) at amino acid position 313 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
