Variant summary

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

The NM_001004432.4(LINGO4):c.1120C>T(p.Arg374Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000136 in 1,613,598 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 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. R374H) has been classified as Uncertain significance.

Ambry Genetics

Oct 01, 2024

The c.1120C>T (p.R374C) alteration is located in exon 2 (coding exon 1) of the LINGO4 gene. This alteration results from a C to T substitution at nucleotide position 1120, causing the arginine (R) at amino acid position 374 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
