Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 15, 2023The c.848C>T (p.A283V) alteration is located in exon 9 (coding exon 9) of the GRAMD1A gene. This alteration results from a C to T substitution at nucleotide position 848, causing the alanine (A) at amino acid position 283 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
