NM_001374828.1:c.4479G>C
Variant summary
Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM2PP3_StrongPP5_Moderate
The NM_001374828.1(ARID1B):c.4479G>C(p.Pro1493Pro) variant causes a splice region, synonymous change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 2/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. P1493P) has been classified as Likely pathogenic.

This variant disrupts the c.4110G nucleotide in the ARID1B gene. Other variant(s) that disrupt this nucleotide have been determined to be pathogenic (PMID: 22405089, 27474218, 28323383). This suggests that this nucleotide is clinically significant, and that variants that disrupt this position are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. 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. This variant has been observed in individual(s) with clinical features of Coffin-Siris syndrome (Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change affects codon 1370 of the ARID1B mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the ARID1B protein. This variant also falls at the last nucleotide of exon 17, which is part of the consensus splice site for this exon. -
