NM_015450.3:c.1884A>C is present at an allele frequency exceeding 1% in gnomAD. In gnomAD v2.1, the total AF is 1.07% (2980/279114 alleles) with 157 homozygotes observed. The grpmax filtering AF is 10.72% in the African/African American population. In gnomAD v4.1, the total AF is 0.59% with 477 homozygotes, and the grpmax FAF is 11.04%. The total AF in v2.1 exceeds the 1% BA1 threshold and is far above the ACMG/AMP 2015 threshold of 5% in the highest subpopulation. This frequency is incompatible with a rare Mendelian disease-causing variant.
NM_015450.3:c.1884A>C is classified as Benign in ClinVar by 7 clinical laboratories (6 reporting 'Benign', 1 reporting 'benign'). Although individual submissions have review status 'criteria provided, single submitter', the concordance across multiple independent clinical laboratories provides supporting evidence for a benign classification.
NM_015450.3:c.1884A>C is a synonymous variant (p.Thr628=). SpliceAI predicts no impact on splicing (max delta score = 0.00). The nucleotide is not highly conserved, as evidenced by the high population frequency (>10% in the African/African American population). BP7 criteria are satisfied: synonymous variant with no predicted splice impact at a non-conserved nucleotide.
gene-specific framework lacked a usable explicit final combination framework, so generic ACMG/AMP 2015 final-combination rules were applied as fallback; applied criteria: BA1 stand-alone benign, BP6 supporting benign, BP7 supporting benign; combination = 1 stand-alone benign + 2 supporting benign, which maps to Benign.

NM_015450.3:c.1884A>C is a synonymous variant (p.Thr628=) in POT1 classified as Benign based on the ACMG/AMP 2015 guidelines.
This variant is present at high frequency in population databases: gnomAD v2.1 reports an allele frequency of 1.07% (2980/279114 alleles, 157 homozygotes), with the highest subpopulation frequency of 11.1% in the African/African American population (grpmax FAF 10.7%); gnomAD v4.1 reports an allele frequency of 0.59% (9370/1588362 alleles, 477 homozygotes), with grpmax FAF of 11.0%. This frequency meets the stand-alone benign criterion BA1.
ClinVar classifies this variant as Benign based on consensus from 7 clinical laboratories (ClinVar variation ID: 475068), providing supporting evidence for a benign classification (BP6).
SpliceAI predicts no impact on splicing (max delta score = 0.00), and the high population frequency indicates the nucleotide is not conserved, satisfying BP7 for this synonymous variant.
No variant-specific functional studies, de novo observations, segregation data, or case-control evidence were identified for this variant. The ClinVar-cited publications (PMID:25741868, PMID:26467025, PMID:28492532) are methodology and guideline papers that do not mention NM_015450.3:c.1884A>C.
