Genes affected

ACTRT2 (HGNC:24026): (actin related protein T2) The protein encoded by this intronless gene belongs to the actin family. Studies have shown that this protein may be involved in cytoskeletal organization similar to other cytoplasmic actin-related protein (ARP) subfamily members. Antibody raised against the human protein has been used to detect the protein by immunoblotting and immunofluorescence microscopy, demonstrating its specific synthesis in the testis, late in spermatid differentiation, and its localization in the calyx.

Nov 17, 2022

The c.139C>T (p.P47S) alteration is located in exon 1 (coding exon 1) of the ACTRT2 gene. This alteration results from a C to T substitution at nucleotide position 139, causing the proline (P) at amino acid position 47 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
