Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 15, 2024The c.1055A>G (p.Q352R) alteration is located in exon 1 (coding exon 1) of the SBSN gene. This alteration results from a A to G substitution at nucleotide position 1055, causing the glutamine (Q) at amino acid position 352 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
