The complete mitochondrial genome data of (Gmelin, 1791) from Malaysia.

(angelwing clam) is a mollusc species found in the coastal areas of Southeast Asia. Despite its economic significance, genetic information on the species is lacking. In this study, a specimen was collected from Kedah, Malaysia, and its complete mitochondrial genome was assembled using whole-genome sequencing data generated on an DNBSEQ-G400 platform. The circular mitochondrial genome of is 18,995 bp in size and contains 12 protein-coding genes (PCGs), 22 tRNAs, two rRNAs, and three control regions (D-loops). All genes are located on the heavy strand. The mitogenome has a base composition of 25.4 % A, 41.5 % T, 22.1% G, and 11 % C, exhibiting a bias towards AT content (66.9 %). The mitochondrial genomes of and 11 other Pholadoidea species were included in a phylogenetic analysis, which indicated that is closely related to . The data reported in this study represents the first time that a mitochondrial genome has been reported. Such data will contribute to the better understanding of genetic relationships between and its relatives, leading to informed conservation and sustainable utilization of the species.
