Genes affected

HOXD9 (HGNC:5140): (homeobox D9) 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 HOXD genes located at 2q31-2q37 chromosome regions. Deletions that removed the entire HOXD gene cluster or 5' end of this cluster have been associated with severe limb and genital abnormalities. The exact role of this gene has not been determined.

HOXD-AS2 (HGNC:43756): (HOXD cluster antisense RNA 2)

ACMG classification

Our verdict: Likely_benign. The variant received -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.23484504).
• BS2: High AC in GnomAdExome4 at 5 AD gene.

The c.418G>A (p.G140S) alteration is located in exon 1 (coding exon 1) of the HOXD9 gene. This alteration results from a G to A substitution at nucleotide position 418, causing the glycine (G) at amino acid position 140 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
