Abstract
Evidence of breast cancer 1 and 2 genes and Estrogen receptor 1 one were found in the genome of the crinoïd : Antedon bifida( an ancestral Echinodermata) in a significant manner.

Key words : Invertebrate, Echinodermata, Antedon bifida, human oncologic marker genes.
Introduction
Many investigations concerning the genome of Antedon bifida have been performed in our laboratory (Ref. 1, 2, 3). It seemed interesting to look for genes implicated in cancerology diagnosis which is a true problem of Human Society.

BRCA1, BRCA2, CASC8, CASC16, ESR1, CRP genes were mainly studied.They encode

for cancer susceptibility proteins as breast, ovarian cancers.
Materials and Methods
Animals (Antedon bifida)
were obtained from « the station marine » of Roscoff (France)
Obtention of crinoïd mRNA
Digestive coeca were excised from the A. bifida body.

A. bifida mRNA was obtained from Uptizol (Interchim). Quality control were operated.
Sequencing
Sequencing was made on Illumina Next Seq 500 with pairedend : 2. 75 bp. Transcriptome was assembled from RNA-Seq fastq files using Trinity v2.1.1 (Ref.4 with default parameters. A BLAST database was created with the assembled transcripts using makeblastdb application from ncbi-blast+ (v2.2.31+). The sequences of transcripts of interest were then blasted against this database using blastn application from ncbi-blast+ (Ref;5) with parameter word_size 7.
Results
Evidence of BRCA1, BRCA2, ESR1 genes occur in Antedon bifida

we complete this table by giving the sequences of BRCA1, BRCA2 transcriptomes :

Conclusion And Discussion
In humans, BRCA1 and BRCA2 genes can be considered as oncologic markers. It is said that mutations of these genes are more common in certain ethnic populations than others ; they increase a woman’s risk of breast and ovarian cancer.

As for ESR1 gene, it encodes an estrogen receptor, a ligand activated transcription factor, composed of several domains important for hormone binding.

To find such genes in an invertebrate remains enigmatic but seems interesting from a point of view of the phylogeny of proteins and genomics
