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 GeneticsNov 07, 2022The c.850G>A (p.E284K) alteration is located in exon 4 (coding exon 2) of the SERPINA12 gene. This alteration results from a G to A substitution at nucleotide position 850, causing the glutamic acid (E) at amino acid position 284 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
