Genes affected

ZAR1L (HGNC:37116): (zygote arrest 1 like) This gene encodes a member of the ZAR1 family that is predominantly expressed in oocytes and early embryos. The protein may function as an RNA regulator in early embryos. [provided by RefSeq, Apr 2010]

The c.134C>G (p.A45G) alteration is located in exon 1 (coding exon 1) of the ZAR1L gene. This alteration results from a C to G substitution at nucleotide position 134, causing the alanine (A) at amino acid position 45 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
