Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 12, 2022The c.274C>T (p.R92C) alteration is located in exon 3 (coding exon 3) of the IGSF5 gene. This alteration results from a C to T substitution at nucleotide position 274, causing the arginine (R) at amino acid position 92 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
