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]
ERCC6L2-AS1 (HGNC:27858): (ERCC6L2 antisense RNA 1)

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.37G>A (p.D13N) alteration is located in exon 1 (coding exon 1) of the ERCC6L2 gene. This alteration results from a G to A substitution at nucleotide position 37, causing the aspartic acid (D) at amino acid position 13 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 13 of the ERCC6L2 protein (p.Asp13Asn). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with ERCC6L2-related conditions. ClinVar contains an entry for this variant (Variation ID: 2261799). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
