Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 15, 2024The c.3599G>T (p.C1200F) alteration is located in exon 12 (coding exon 11) of the IGSF3 gene. This alteration results from a G to T substitution at nucleotide position 3599, causing the cysteine (C) at amino acid position 1200 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
