Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2021The c.2578A>G (p.S860G) alteration is located in exon 19 (coding exon 18) of the SEMA6A gene. This alteration results from a A to G substitution at nucleotide position 2578, causing the serine (S) at amino acid position 860 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
