RCV000780684 | SCV000918151 | likely pathogenic | Metaphyseal chondrodysplasia, McKusick type | 2018-11-15 | criteria provided, single submitter | clinical testing | Variant summary: RMRP n.-14_-2dup13 variant involves the duplication of 13 nucleotides in the promoter region of RMRP, which is located between the TATA box (-33 to -25) and the transcription initiation site. Multiple duplication variants in this promoter region have been reported pathogenic (internally and in HGMD). The variant was absent in 119274 control chromosomes (gnomAD). To our knowledge, no occurrence of n.-14_-2dup13 in individuals affected with Cartilage-Hair Hypoplasia and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic. |
