RCV002471585 | SCV002768963 | uncertain significance | Perrault syndrome 2 | 2022-02-02 | criteria provided, single submitter | clinical testing | A heterozygous deletion variant was identified, NM_012208.3(HARS2):c.1450_1451delinsC in exon 12 of 13 of the HARS2 gene. This deletion is predicted to cause a frameshift from amino acid position 484 introducing a stop codon 35 residues downstream, NP_036340.1(HARS2):p.(Ser484Profs*35), resulting in an extension of the reading frame. The variant is present in the gnomAD population database at a frequency of 0.0025% (7 heterozygotes, 0 homozygotes). It has not been previously observed in clinical cases. No other variants predicted to cause an extension of the reading frame have been reported in a clinical testing setting. Based on information available at the time of curation, this variant has been classified as a VARIANT of UNCERTAIN SIGNIFICANCE (VUS). |
