Submissions by phenotype
not specified Uncertain:1
The c.730G>A (p.G244R) alteration is located in exon 8 (coding exon 6) of the SERPINB2 gene. This alteration results from a G to A substitution at nucleotide position 730, causing the glycine (G) at amino acid position 244 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
