Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 07, 2022The c.994T>C (p.Y332H) alteration is located in exon 8 (coding exon 8) of the STPG2 gene. This alteration results from a T to C substitution at nucleotide position 994, causing the tyrosine (Y) at amino acid position 332 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
