Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2022The c.436C>G (p.Q146E) alteration is located in exon 4 (coding exon 4) of the PHACTR2 gene. This alteration results from a C to G substitution at nucleotide position 436, causing the glutamine (Q) at amino acid position 146 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
