However, this variant was confirmed in two sisters with infertility due to metaphase 1 oocyte maturation arrest by the Broad Institute Rare Genomes Project and found to be paternally-inherited. This variant is comprised of two cis single nucleotide variants leading to two amino acid substitutions. Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein.

The p.[Leu345Phe; Asn347Asp] variant in TUBB8 has not been previously reported in individuals with disease or in large population studies. However, this variant was confirmed in two sisters with infertility due to metaphase 1 oocyte maturation arrest by the Broad Institute Rare Genomes Project and found to be paternally-inherited. This variant is comprised of two cis single nucleotide variants leading to two amino acid substitutions. Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.[Leu345Phe; Asn347Asp] variant is uncertain. ACMG/AMP Criteria applied: PM2, PP4.
