Variant 6-89644075-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2PP2BP4_Moderate

The NM_014611.3(MDN1):c.16721C>T(p.Ala5574Val) variant causes a missense change. The variant allele was found at a frequency of 0.00000205 in 1,461,862 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. 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. A5574T) has been classified as Uncertain significance.

The c.16721C>T (p.A5574V) alteration is located in exon 102 (coding exon 102) of the MDN1 gene. This alteration results from a C to T substitution at nucleotide position 16721, causing the alanine (A) at amino acid position 5574 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
