==== Relational Information Regarding Orthologs and Paralogs ====
The NBPF8 gene is a part of a gene family, the neuroblastoma breakpoint family, and therefore has many paralogs within this family. Outside of genes within the neuroblastoma breakpoint family, and excluding uncharacterized proteins, there is only one paralog associated with NBPF8 which is myomegalin; myomegalin isoform 16 has the highest percent identity of 32.94%. Something notable is that myomegalin has orthologs in sharks and rays (bony fish) which extends further back evolutionarily than NBPF8’s orthologs; as a note, the neuroblastoma breakpoint family as a whole does not extend further evolutionarily than NBPF8 individually.
There are only eight direct orthologs of NBPF8; evolutionary speaking, the furthest species from humans (”Homo sapiens”) these orthologs of NBPF8 are found in, are birds. The following will depict what each of the orthologs is and what its three letter code followed by “_NBPF8” represents as these codes will to be used to depict which protein sequence is which in a more concise manner:
* Cni_NBPF8: the NBPF8 protein found in ”Caloenas nicobarica” (the Nicobar pigeon)
* Cci_NBPF8: the NBPF8 protein found in ”Cinclus cinclus” (the White-throated dipper)
* Hru_NBPF8: the NBPF8 protein found in ”Hirundo rustica” (the Barn swallow)
* Pat_NBPF8: the NBPF8 protein found in ”Poecile atricapillus” (the Black-capped chickadee)
* Ana_NBPF8: the NBPF8 protein found in ”Aotus nancymaae” (the Ma’s night monkey)
* Ppa_NBPF8: the NBPF8 protein found in ”Pan paniscus” (the Pygmy chimpanzee)
* Hsa_NBPF8: the NBPF8 protein found in ”Homo sapiens” (the Human)

==== Evolutionary Context ====
NBPF8 first appeared in birds, and all of the members of the neuroblastoma breakpoint family also have orthologs that only extend as far back in the evolutionary tree as NBPF8; there are no members of the family that extend further back than aves. In fact, NBPF8 is the only gene within the neuroblastoma breakpoint family (of which contains 22 genes total) that has orthologs further back evolutionarily than mammals.

NBPF8
NBPF8 (transcript variant 1 in Homo sapiens), a member of the neuroblastoma breakpoint family (NBPF) (link to Wikipedia page), is located on human chromosome 1 and spans 7,256 base pairs; its coding sequence, however, spans 2,828 base pairs. On the first chromosome, its specific region to which it belongs can be noted as 1p11.2[1], its accession number is NM_001037501, and it is located on the + strand[2]. Additionally, this gene has a molecular weight of ~109 kDa[3].
Transcription
Within the NCBI Build 37.2, a single genomic continuum on the assembly of the gene; one of the open reading frames is NBPF8. This gene contains, within the first coding exon, there are deletion a deletion of two nucleotides therefore causing a frameshift mutation[4]. As far as variety, there are only two isoforms other than NBPF8 transcript variant 1 and those are transcript variants X1 and X[5].
Protein
The NBPF8 protein spans 942 amino acids and its accession number is NP_001032590. The NBPF family is identified via repeated copies of DUF1220 protein domains, also known as Olduvai domains[6]. These domains are an incredibly important factor in determining what this gene codes for/what its function really is.
Clinical Significance
Where most Olduvai domains (link to Wikipedia page) are located, in 1q21.1, gene copy number variations in this region of the chromosome have been identified in certain diseases, both developmental and neurogenetic, consisting of micro- and macrocephaly, autism, schizophrenia, cognitive disability, congenital heart disease, neuroblastoma, and congenital kidney and urinary tract anomalies, as well as some types of cancer[7]. The expression of the NBPF8 gene has been detected in the skin, the lymph node, and about 25 other tissues as well.
