Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 15, 2023The c.1334A>G (p.K445R) alteration is located in exon 11 (coding exon 11) of the STPG2 gene. This alteration results from a A to G substitution at nucleotide position 1334, causing the lysine (K) at amino acid position 445 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
