Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_018029.4(EBLN2):​c.478A>G​(p.Arg160Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000186 in 1,613,834 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. R160S) has been classified as Uncertain significance.

Genes affected
EBLN2 (HGNC:25493): (endogenous Bornavirus like nucleoprotein 2)
PPP4R2 (HGNC:18296): (protein phosphatase 4 regulatory subunit 2) The protein encoded by this gene is a regulatory subunit of the serine/threonine-protein phosphatase 4 complex. In addition to being required for efficient DNA double strand break repair, this complex plays a role in organization of microtubules at centrosomes and processing of spliceosomal snRNPs. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2015]

The c.478A>G (p.R160G) alteration is located in exon 1 (coding exon 1) of the EBLN2 gene. This alteration results from a A to G substitution at nucleotide position 478, causing the arginine (R) at amino acid position 160 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
