Final classification
VUS
c.34_35delGGTGGinsTGTGC

NM_033360.3:c.34_35delGGTGGinsTGTGC is a complex in-frame indel in KRAS affecting codons 12-13 within the P-loop/G1 motif, a critical functional domain and well-established mutational hotspot. Most ACMG/AMP criteria could not be assessed because variant normalization failed during the evidence retrieval phase (VariantValidator unavailable), resulting in absent population frequency data, absent ClinVar classifications, and absent functional evidence in the case files.

Basis gene-specific framework lacked a usable explicit final combination framework, so generic ACMG/AMP 2015 final-combination rules were applied as fallback; applied criteria: none; combination = no applied criteria, which maps to VUS.

c.34_35delGGTGGinsTGTGC

NM_033360.3:c.34_35delGGTGGinsTGTGC is a complex in-frame indel in KRAS affecting codons 12-13 within the P-loop/G1 motif, a critical functional domain and well-established mutational hotspot. Most ACMG/AMP criteria could not be assessed because variant normalization failed during the evidence retrieval phase (VariantValidator unavailable), resulting in absent population frequency data, absent ClinVar classifications, and absent functional evidence in the case files. PVS1 is not applicable: KRAS germline disorders (RASopathies: Noonan syndrome, CFC syndrome) are caused by gain-of-function activating mutations, not loss-of-function, and this is an in-frame indel that does not trigger nonsense-mediated decay.1 Re-adjudication is recommended after successful variant normalization to obtain gnomAD allele frequencies, ClinVar classifications, SpliceAI scores, and to correct the HGVS notation (which has a coordinate-range vs deletion-sequence-length mismatch flagged by VariantValidator). PM1 (hotspot domain), PM2 (absent from population), and PM4 (in-frame indel in non-repeat region) are likely to be the most informative criteria once data are available.
