Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2023The c.43C>G (p.R15G) alteration is located in exon 2 (coding exon 2) of the GRAMD1B gene. This alteration results from a C to G substitution at nucleotide position 43, causing the arginine (R) at amino acid position 15 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
