Genes affected
RECQL4 (HGNC:9949): (RecQ like helicase 4) The protein encoded by this gene is a DNA helicase that belongs to the RecQ helicase family. DNA helicases unwind double-stranded DNA into single-stranded DNAs and may modulate chromosome segregation. This gene is predominantly expressed in thymus and testis. Mutations in this gene are associated with Rothmund-Thomson, RAPADILINO and Baller-Gerold syndromes. [provided by RefSeq, Jan 2010]

ACMG classification
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 8 ACMG points.
PVS1
?
Splicing variant, NOT destroyed by nmd, known LOF gene, truncates exone, which is 0.036118004 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.
PM2
?
Very rare variant in population databases, with high coverage;
PP3
?
Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
PP5
?
Variant 8-144515325-C-A is Pathogenic according to our data. Variant chr8-144515325-C-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 225453.Status of the report is criteria_provided_single_submitter, 1 stars.
