Genes affected

HMX3 (HGNC:5019): (H6 family homeobox 3) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in ear development and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including embryo implantation; maternal process involved in female pregnancy; and neuromuscular process controlling balance. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Aug 30, 2021

The c.212C>T (p.A71V) alteration is located in exon 1 (coding exon 1) of the HMX3 gene. This alteration results from a C to T substitution at nucleotide position 212, causing the alanine (A) at amino acid position 71 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
