Variant 22-50503678-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The ENST00000474879.7(LMF2):c.1837C>T(p.Arg613Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000105 in 1,593,918 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/20 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. R613H) has been classified as Uncertain significance.

Ambry Genetics

Sep 17, 2021

The c.1837C>T (p.R613C) alteration is located in exon 14 (coding exon 14) of the LMF2 gene. This alteration results from a C to T substitution at nucleotide position 1837, causing the arginine (R) at amino acid position 613 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
