Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong
The NM_004260.4(RECQL4):c.2463+3T>C variant causes a splice region, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000472 in 1,568,178 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★★).

Rothmund-Thomson syndrome type 2 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | St. Jude Molecular Pathology, St. Jude Children's Research Hospital | Aug 29, 2023 | The RECQL4 c.2463+3T>C intronic change results in a T to C substitution at the +3 position of intron 15 of the RECQL4 gene. This variant is predicted to disrupt the consensus splice site however RNA studies have not been performed. This variant has a maximum subpopulation frequency of 0.11% in gnomAD v2.1.1. To our knowledge, this variant has not been reported in the literature in individuals with RECQL4-associated disorders. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. - |
Baller-Gerold syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Nov 04, 2024 | This sequence change falls in intron 14 of the RECQL4 gene. It does not directly change the encoded amino acid sequence of the RECQL4 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs538535710, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with RECQL4-related conditions. ClinVar contains an entry for this variant (Variation ID: 239729). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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. - |
