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]

MNX1-AS2 (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM1: In a DNA_binding_region Homeobox (size 59) in uniprot entity MNX1_HUMAN there are 16 pathogenic changes around while only 0 benign (100%) in NM_005515.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.842
