Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2021The c.3704A>G (p.Q1235R) alteration is located in exon 1 (coding exon 1) of the IRS1 gene. This alteration results from a A to G substitution at nucleotide position 3704, causing the glutamine (Q) at amino acid position 1235 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
