Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 21, 2023The c.3404G>A (p.R1135Q) alteration is located in exon 21 (coding exon 20) of the IGSF22 gene. This alteration results from a G to A substitution at nucleotide position 3404, causing the arginine (R) at amino acid position 1135 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
