ARMC5 and meningioma: Besides PBMAH, ARMC5 alterations affecting both alleles have been implicated in the development of meningiomas: p.(Thr503Profs*34) somatic event added to the germline already known p.(Ala110Argfs*9) variant in a first patient [22]; tumoral loss of heterozygosity (LOH) along with the germline p.(Arg267*) variant in another patient [26].
