Submissions by phenotype
not specified Uncertain:1
The p.Arg513Cys variant in ILDR1 has not been previously reported in individuals with hearing loss, but it has been identified in 2/11254 Latino chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs 767668911). Although this variant has been seen in the general population, its f requency is not high enough to rule out a pathogenic role. The arginine (Arg) at position 513 is highly conserved in mammals with two species (Green monkey, les ser Egyptian jerboa) having a cysteine (Cys), supporting that this change at thi s position may be tolerated. Additional computational prediction tools do not p rovide strong support for or against an impact to the protein. In summary, while the clinical significance of the p.Arg513Cys variant is uncertain, the conserva tion data suggest that it is more likely to be benign. -
Inborn genetic diseases Uncertain:1
The c.1537C>T (p.R513C) alteration is located in exon 7 (coding exon 7) of the ILDR1 gene. This alteration results from a C to T substitution at nucleotide position 1537, causing the arginine (R) at amino acid position 513 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
