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]

The c.953C>T (p.A318V) alteration is located in exon 9 (coding exon 9) of the ASTL gene. This alteration results from a C to T substitution at nucleotide position 953, causing the alanine (A) at amino acid position 318 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
