Variant 4-48490680-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 ENST00000327939.4(ZAR1):c.389G>A(p.Arg130Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000685 in 1,314,470 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/20 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. R130W) has been classified as Uncertain significance.

Genes affected

ZAR1 (HGNC:20436): (zygote arrest 1) This maternal effect gene is oocyte-specific and encodes a protein that is thought to function in the initiation of embryogenesis. A similar protein in mouse is required for female fertility. [provided by RefSeq, Jul 2013]

The c.389G>A (p.R130Q) alteration is located in exon 1 (coding exon 1) of the ZAR1 gene. This alteration results from a G to A substitution at nucleotide position 389, causing the arginine (R) at amino acid position 130 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
