Genes affected
SERPINA12 (HGNC:18359): (serpin family A member 12) Predicted to enable serine-type endopeptidase inhibitor activity. Predicted to be involved in negative regulation of endopeptidase activity. Predicted to act upstream of or within negative regulation of gluconeogenesis; positive regulation of signal transduction; and regulation of lipid metabolic process. Predicted to be located in plasma membrane. Predicted to be active in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.802A>G (p.I268V) alteration is located in exon 4 (coding exon 2) of the SERPINA12 gene. This alteration results from a A to G substitution at nucleotide position 802, causing the isoleucine (I) at amino acid position 268 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
