Genes affected
MNX1 (HGNC:4979): (motor neuron and pancreas homeobox 1) This gene encodes a nuclear protein, which contains a homeobox domain and is a transcription factor. Mutations in this gene result in Currarino syndrome, an autosomic dominant congenital malformation. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 06, 2022The c.1132G>A (p.A378T) alteration is located in exon 3 (coding exon 3) of the MNX1 gene. This alteration results from a G to A substitution at nucleotide position 1132, causing the alanine (A) at amino acid position 378 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
