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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 27, 2022The c.838G>A (p.G280S) alteration is located in exon 8 (coding exon 8) of the ASTL gene. This alteration results from a G to A substitution at nucleotide position 838, causing the glycine (G) at amino acid position 280 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
