Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 7P and 4B. PM5PP3_StrongPP5BS2

The NM_005664.4(MKRN3):​c.982C>T​(p.Arg328Cys) variant causes a missense change. The variant allele was found at a frequency of 0.00000547 in 1,461,892 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R328H) has been classified as Likely pathogenic.

Genes affected
MKRN3 (HGNC:7114): (makorin ring finger protein 3) The protein encoded by this gene contains a RING (C3HC4) zinc finger motif and several C3H zinc finger motifs. This gene is intronless and imprinted, with expression only from the paternal allele. Disruption of the imprinting at this locus may contribute to Prader-Willi syndrome. An antisense RNA of unknown function has been found overlapping this gene. [provided by RefSeq, Jul 2008]
