Variant summary
Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PVS1PP5_Very_Strong
The NM_000124.4(ERCC6):c.2096_2097insC(p.Leu700ValfsTer60) variant causes a frameshift change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000684 in 1,461,852 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. T699T) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jul 30, 2023 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 190159). This premature translational stop signal has been observed in individual(s) with clinical features of Cockayne syndrome (PMID: 28170084). This variant is present in population databases (rs774791374, gnomAD 0.002%). This sequence change creates a premature translational stop signal (p.Leu700Valfs*60) in the ERCC6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ERCC6 are known to be pathogenic (PMID: 18628313, 29572252). - |
