Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2023The c.191A>G (p.Q64R) alteration is located in exon 2 (coding exon 2) of the SCGB2B2 gene. This alteration results from a A to G substitution at nucleotide position 191, causing the glutamine (Q) at amino acid position 64 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
