Classification rationale
1

The BCOR c.4677C>T (p.Asp1559=) variant has been reported in ClinVar with benign and likely benign classifications from two single submitters.

clinvar ↗
2

This variant is present in gnomAD v2.1 and v4.1 at low frequency (0.00444%-0.00448%), which is below the default BS1 threshold of 0.3% and BA1 threshold of 1.0%, so population frequency alone does not establish a stand-alone or strong benign criterion.

3

SpliceAI predicts no significant splice impact for this synonymous variant, with a maximum delta score of 0.00, supporting a benign splicing interpretation consistent with BP7.

4

Cancer Hotspots did not identify a statistically significant hotspot at BCOR codon 1559, which does not support PM1.
