This variant is present at high frequency in gnomAD population databases. In gnomAD v2.1: overall AF=0.4166% (1169/280568 alleles), African/African American subpopulation AF=4.23% (1052/24896 alleles), grpmax FAF=4.01%, with 16 homozygotes observed. In gnomAD v4.1: overall AF=0.2185% (3498/1600686 alleles), African/African American subpopulation AF=4.17% (3108/74566 alleles), grpmax FAF=4.05%, with 54 homozygotes observed. The grpmax filtering allele frequency exceeds the BA1 threshold of >1% in both datasets, and the observation of multiple homozygotes confirms this is a common population polymorphism incompatible with a Mendelian disease-causing role.
SpliceAI predicts no splicing impact for this intronic variant (max delta score = 0.00), indicating that the c.6330+19G>A substitution does not create or disrupt a splice site. In the absence of applicable missense prediction tools (REVEL and BayesDel not available for intronic variants), SpliceAI provides the primary computational evidence for this variant class, and its prediction of no splicing effect supports a benign interpretation.
ClinVar reports this variant as Benign (6 clinical laboratories: GeneDx, PreventionGenetics, ARUP Laboratories, KCCC/NGS Laboratory, Labcorp/Invitae, and Center for Genomic Medicine Rigshospitalet). Although review status is 'criteria provided, single submitter' and no expert panel review is recorded, the unanimous classification as Benign across multiple independent clinical laboratories provides supporting evidence for a benign interpretation.
BA1 (stand-alone benign) is met: the variant has grpmax filtering allele frequency of 4.01% (gnomAD v2.1) and 4.05% (gnomAD v4.1), exceeding the 1% stand-alone benign threshold, with 16+54 homozygotes observed. Under both the León-Castillo custom POLE framework (rule: 'BA1') and generic ACMG/AMP 2015 combination rules, BA1 alone suffices for a Benign classification. BP4 and BP6 (both supporting benign) provide additional concordant evidence but are not required for the call.

NM_006231.4:c.6330+19G>A is classified as Benign.
BA1 is met: the variant has a grpmax filtering allele frequency of 4.01% (gnomAD v2.1) and 4.05% (gnomAD v4.1), exceeding the 1% stand-alone benign threshold. The variant is observed in 1169/280568 alleles (16 homozygotes) in gnomAD v2.1 and 3498/1600686 alleles (54 homozygotes) in gnomAD v4.1, with highest frequency in the African/African American population (4.23% v2.1, 4.17% v4.1).
BP4 (supporting benign) is met: SpliceAI predicts no splicing impact (max delta = 0.00).
BP6 (supporting benign) is met: ClinVar reports this variant as Benign from 6 independent clinical laboratories.
All pathogenic criteria were assessed and are either not met, not applicable, or not supported by the available evidence. PVS1 is not applicable (deep intronic, not a null variant). PM1 is not applicable (not an exonuclease-domain missense hotspot). PM2 is not met (allele frequency exceeds 0.1%). PP3 is not met (SpliceAI delta = 0, no REVEL score available).
BA1 alone satisfies the Benign classification rule under both the León-Castillo custom POLE framework and generic ACMG/AMP 2015 combination rules.
