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-AS1 (HGNC:48954): (MNX1 antisense RNA 1 (head to head))

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 18 ACMG points.

PVS1
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 43 pathogenic variants in the truncated region.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 7-157010297-T-TG is Pathogenic according to our data. Variant chr7-157010297-T-TG is described in ClinVar as Pathogenic. ClinVar VariationId is 435883.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
