Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_152463.4(EME1):c.197C>T(p.Pro66Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000719 in 1,614,180 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 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. P66A) has been classified as Uncertain significance.

Genes affected

EME1 (HGNC:24965): (essential meiotic structure-specific endonuclease 1) This gene encodes a protein that complexes with methyl methanesulfonate-sensitive UV-sensitive 81 protein to form an endonuclease complex. The encoded protein interacts with specifc DNA structures including nicked Holliday junctions, 3'-flap structures and aberrant replication fork structures. This protein may be involved in repairing DNA damage and in maintaining genomic stability. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Oct 2009]

EME1 links:

LRRC59 (HGNC:28817): (leucine rich repeat containing 59) Enables RNA binding activity and cadherin binding activity. Predicted to be involved in positive regulation of Ras protein signal transduction and signal transduction. Located in endoplasmic reticulum and mitochondrial nucleoid.

Collection Method: clinical testing

The c.197C>T (p.P66L) alteration is located in exon 2 (coding exon 1) of the EME1 gene. This alteration results from a C to T substitution at nucleotide position 197, causing the proline (P) at amino acid position 66 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
