Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2024The c.3049C>T (p.R1017C) alteration is located in exon 19 (coding exon 18) of the IGSF22 gene. This alteration results from a C to T substitution at nucleotide position 3049, causing the arginine (R) at amino acid position 1017 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
