Variant chr1-54806207-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_001110533.2(CIMAP2):c.91G>A(p.Val31Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00011 in 1,540,246 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. V31L) has been classified as Uncertain significance.

Ambry Genetics

Aug 23, 2021

The c.91G>A (p.V31M) alteration is located in exon 1 (coding exon 1) of the LEXM gene. This alteration results from a G to A substitution at nucleotide position 91, causing the valine (V) at amino acid position 31 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
