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]

This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces serine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 380 of the MNX1 protein (p.Ser380Ala). This variant has not been reported in the literature in individuals affected with MNX1-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
