RCV001007577 | SCV001167207 | uncertain significance | Treacher Collins syndrome 1 | 2019-10-02 | criteria provided, single submitter | clinical testing | This variant has been previously identified in a mildly affected patient and an unaffected father. Another variant at this position (p.Ile14Phe) has been reported in an affected individual. The Ile14 residue is believed to be important to the formation of hydrophobic contacts between Lis1 homodimers. Although p.Ile14Met is absent from healthy population datasets, other missense variants at this and other surrounding residues are present, suggesting that missense variation in the Lis1 domain may be tolerated. Three bioinformatic tools queried predict that this substitution would be probably damaging, and the isoleucine residue at this position is evolutionarily conserved across all species assessed with the exception of the Chinese tree shrew. Due to the identification of this variant in unaffected individuals and the lack of functional evidence that this variant is deleterious, we consider the clinical significance of c.42C>G uncertain at this time. |
