Genes affected

ASTL (HGNC:31704): (astacin like metalloendopeptidase) Predicted to enable aspartic-type peptidase activity; glutamic-type peptidase activity; and metalloendopeptidase activity. Predicted to be involved in several processes, including negative regulation of binding activity of sperm to zona pellucida; positive regulation of protein processing; and prevention of polyspermy. Predicted to be located in cortical granule and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Jul 09, 2021

The c.628A>G (p.I210V) alteration is located in exon 6 (coding exon 6) of the ASTL gene. This alteration results from a A to G substitution at nucleotide position 628, causing the isoleucine (I) at amino acid position 210 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
