Added comment: MN1 is associated to CEBALID syndrome (MIM# 618774), and many individuals have been reported with a high-arched palate. So far, 2 individuals have been reported with cleft palate, one with a severe form of the condition, associated with a truncating variant at the C-terminal, which are known to result in gain of function (PMID 31834374). And more recently, a NMD variant, established by RT-PCR and Western Blot, has been identified in a family with cleft palate and conductive hearing loss, but no ID and no other dysmorphic features (PMID 33351070). PMID 33351141 mentions that LoF is likely associated with a milder phenotype despite the high MAF of some NMD in the population, as these are in low complexity region.
