The heterozygous p.Phe94Leu variant in TUBD1 was identified by our study in one individual with multiple congenital anomalies including Duane retraction syndrome, premature ovarian insufficiency, scoliosis, hemivertebrae, polysyndactyly and hypoplasia of the toes, neonatal necrotizing enterocolitis, and inguinal hernia, via a collaborative study between the Broad Institute's Center for Mendelian Genomics and the Engle lab (https://kirbyneuro.org/EngleLab/). To our knowledge, the p.Phe94Leu variant in TUBD1 has not been previously reported in individuals with Mendelian disease. This variant was absent from large population studies. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Phe94Leu variant is uncertain. ACMG/AMP Criteria applied: PM2_Supporting (Richards 2015). -
