Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The ENST00000327939.4(ZAR1):ā€‹c.44C>Gā€‹(p.Pro15Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000441 in 1,361,712 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P15L) 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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 17, 2023The c.44C>G (p.P15R) alteration is located in exon 1 (coding exon 1) of the ZAR1 gene. This alteration results from a C to G substitution at nucleotide position 44, causing the proline (P) at amino acid position 15 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
