Genes affected

WDR97 (HGNC:26959): (WD repeat domain 97) The function and protein-coding potential of this gene is unknown. The exon combination is based on AB058778.1 for which two possible open reading frames can be predicted (with start codons at nucleotide 26 or 2614). The position of the first ORF stop codon is consistent with a prediction of nonsense-mediated decay. Given the observation of the first ORF and its length, a predicted translation of the second ORF is inconsistent with the translation leaky scanning theory. Therefore, this gene is represented as a non-protein-coding transcript. [provided by RefSeq, Oct 2008]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BP6: Variant 8-144109537-G-A is Benign according to our data. Variant chr8-144109537-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 2658973.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.146 with no splicing effect.
