Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2023The c.2654C>T (p.T885I) alteration is located in exon 21 (coding exon 21) of the SRGAP3 gene. This alteration results from a C to T substitution at nucleotide position 2654, causing the threonine (T) at amino acid position 885 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
