Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.3272G>T (p.S1091I) alteration is located in exon 22 (coding exon 22) of the SRGAP3 gene. This alteration results from a G to T substitution at nucleotide position 3272, causing the serine (S) at amino acid position 1091 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
