Infertility and Recurrent Pregnancy Loss v0.151 ACTL7A Jasmine Chew changed review comment from: Literature in OMIM entry- PubMed: 32923619, 34727571, 36593593, 37004249- different biallelic variants reported in >3 unrelated infertile men

Other papers:
i)PMID: 37991128 (2025)- two infertile males with com het p.R373H/p.G402S and hom p.R373C. All located within actin domain and predicted to be pathogenic. The protein expression of actin-like protein 7A was absent in affected spermatozoa by using immunofluorescence staining and western blotting, confirming the pathogenicity of the variants.

ii)PMID: 36574082 (2023)- two infertile brothers with hom p.D75A with teratozoospermia and fertilization failure. Immunofluorescence revealed that ACTL7A protein was degraded in sperms of patients. Transmission electron microscopy (TEM) analysis of sperms from the infertile patients showed that the irregular perinuclear theca (PT) and acrosomal ultrastructural defects. The variant also caused abnormal localization and reduced the expression of PLCZ1 in sperms of the patients.

iii) PMID: 35921706 (2022)- Actl7a gene knockout (KO) mice led to malformed formation of sperm acrosomes, male infertility, fertilization failure during in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), and reduced sperm-zona pellucida (ZP) binding ability. Localization of the zona pellucida binding protein (ZPBP) was altered in the sperm of Actl7a homozygous KO male mice.
