Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 27, 2023The c.828C>G (p.I276M) alteration is located in exon 7 (coding exon 7) of the STPG2 gene. This alteration results from a C to G substitution at nucleotide position 828, causing the isoleucine (I) at amino acid position 276 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
