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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2021The c.706C>A (p.R236S) alteration is located in exon 2 (coding exon 2) of the HMX3 gene. This alteration results from a C to A substitution at nucleotide position 706, causing the arginine (R) at amino acid position 236 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
