Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2024The c.346C>T (p.R116C) alteration is located in exon 5 (coding exon 5) of the GRAMD1A gene. This alteration results from a C to T substitution at nucleotide position 346, causing the arginine (R) at amino acid position 116 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
