Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2021The c.770C>T (p.S257L) 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 770, causing the serine (S) at amino acid position 257 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
