Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3

The NM_014611.3(MDN1):​c.16601G>T​(p.Arg5534Leu) variant causes a missense, splice region change. The variant allele was found at a frequency of 0.000283 in 1,586,718 control chromosomes in the GnomAD database, with no homozygous occurrence. 2/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R5534P) has been classified as Uncertain significance.
