Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2024The c.1916G>A (p.R639Q) alteration is located in exon 14 (coding exon 14) of the STRN4 gene. This alteration results from a G to A substitution at nucleotide position 1916, causing the arginine (R) at amino acid position 639 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
