AWK - print output

I have a data table in tsv format, the content of the file looks like the following.

    Gene_stable_ID  Gene_stable_ID_version  Transcript_stable_ID    Transcript_stable_ID_version    Gene_name   Gene_type
ENSMUSG00000064372  ENSMUSG00000064372.1    ENSMUST00000082423  ENSMUST00000082423.1    Cyp Mt_tRNA
ENSMUSG00000064371  ENSMUSG00000064371.1    ENSMUST00000082422  ENSMUST00000082422.1    mt-Tt   unprocessed_pseudogene
ENSMUSG00000064370  ENSMUSG00000064370.1    ENSMUST00000082421  ENSMUST00000082421.1    Cyp processed_pseudogene
ENSMUSG00000064369  ENSMUSG00000064369.1    ENSMUST00000082420  ENSMUST00000082420.1    Cyp pseudogene

My goal here is to get the rows where the 'Gene name' is 'Cyp' and 'Gene type' is 'protein_coding' or 'pseudogene' or 'processed_pseudogene' or 'processed_pseudogene'.

I used awk command to do this, like this.

grep -i Cyp mapping.tsv | awk -F "\t" '{ if($NF == "protein_coding" || $NF == "pseudogene" || $NF == "processed_pseudogene") { print }}'

Here, I only get the 'Gene name' - Cyp and 'Gene type' - protein_coding, the 'pseudogene' part is ignored.

Can you help me figure this out? Thanks.
