Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2024The c.3257A>T (p.K1086M) alteration is located in exon 22 (coding exon 22) of the SRGAP3 gene. This alteration results from a A to T substitution at nucleotide position 3257, causing the lysine (K) at amino acid position 1086 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
