Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2021The c.958G>A (p.A320T) alteration is located in exon 10 (coding exon 10) of the GRAMD1B gene. This alteration results from a G to A substitution at nucleotide position 958, causing the alanine (A) at amino acid position 320 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
