Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 30, 2020 | The c.1523T>G (p.L508R) alteration is located in exon 16 (coding exon 15) of the DDX11 gene. This alteration results from a T to G substitution at nucleotide position 1523, causing the leucine (L) at amino acid position 508 to be replaced by an arginine (R). Based on data from the Genome Aggregation Database (gnomAD), the DDX11 c.1523T>G alteration was not observed, with coverage at this position. The c.1523T>G alteration in DDX11 was previously detected in trans with c.1949-1G>A in two sisters with Warsaw breakage syndrome via clinical exome sequencing of the proband and parents. Both sisters were reported to have pre- and postnatal growth restriction, microcephaly, intellectual disability, sensorineural hearing loss with cochlear abnormalities, and facial dysmorphic features. In addition, the sisters had early menarche at 8 and 10 years of age, bilateral small thumbs, and the younger, more severely affected sister had small fibulae. Both sisters also showed a small increase in spontaneous and DEB-induced chromosome breaks that were not consistent with Fanconi anemia (Eppley, 2017). The p.L508 amino acid is conserved in available vertebrate species. The in silico prediction for the p.L508R alteration is inconclusive. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
