Genes affected
ERCC6L2 (HGNC:26922): (ERCC excision repair 6 like 2) This gene encodes a member of the Snf2 family of helicase-like proteins. The encoded protein may play a role in DNA repair and mitochondrial function. Mutations in this gene have been associated with bone marrow failure syndrome 2. Alternatively spliced transcript variants that encode different protein isoforms have been described. [provided by RefSeq, Apr 2014]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 12, 2023This sequence change creates a premature translational stop signal (p.Arg655*) in the ERCC6L2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ERCC6L2 are known to be pathogenic (PMID: 24507776, 27185855, 29146883, 29987015). This variant is present in population databases (rs147948835, gnomAD 0.03%). This premature translational stop signal has been observed in individual(s) with bone marrow failure (PMID: 24507776, 27185855, 29146883). ClinVar contains an entry for this variant (Variation ID: 125449). For these reasons, this variant has been classified as Pathogenic. -
Pathogenic, criteria provided, single submitterclinical testingGeneDxMay 16, 2023Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Published functional studies demonstrate a damaging effect of this variant, which formed abnormal cytoplasmic aggregates and localized to autophagic vacuoles (Tummala et al., 2014); This variant is associated with the following publications: (PMID: 24507776, 29146883, 27185855, 37011912) -
