RCV001993383 | SCV002227961 | pathogenic | Alstrom syndrome | 2021-05-11 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. Retrotransposon insertions including LINE1 (L1), Alu, and SVA (SINE-VNTR-Alu) have been reported to be disease-causing through disruption of either a coding region or splice site (PMID: 19763152, 20307669, 22406018) and loss-of-function variants in ALMS1 are known to be pathogenic (PMID: 17594715). This variant has not been reported in the literature in individuals with ALMS1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change inserts a large fragment of DNA, likely a transposable element, in exon 16 of the ALMS1 gene (c.10768_10769ins?), causing a frameshift at codon 3590 (p.Glu3590fs). The exact size and sequence of the insertion cannot be determined by the current assay. However, the insertion is expected to result in an absent or disrupted protein product. |
