Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2BP4_StrongBS1_Supporting

The NM_207341.4(ZP1):c.211C>G(p.Arg71Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000421 in 1,614,132 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. R71Q) has been classified as Likely benign.

Genes affected

ZP1 (HGNC:13187): (zona pellucida glycoprotein 1) The zona pellucida is an extracellular matrix that surrounds the oocyte and early embryo. It is composed primarily of three or four glycoproteins with various functions during fertilization and preimplantation development. The protein encoded by this gene ensures the structural integrity of the zona pellucida. Mutations in this gene are a cause of oocyte maturation defect and infertility.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.03090331).

BS1

Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.00021 (32/152256) while in subpopulation AMR AF= 0.00203 (31/15298). AF 95% confidence interval is 0.00147. There are 0 homozygotes in gnomad4. There are 23 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Collection Method: clinical testing

The c.211C>G (p.R71G) alteration is located in exon 2 (coding exon 2) of the ZP1 gene. This alteration results from a C to G substitution at nucleotide position 211, causing the arginine (R) at amino acid position 71 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
