Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 15, 2024The c.205A>C (p.I69L) alteration is located in exon 3 (coding exon 3) of the IGSF5 gene. This alteration results from a A to C substitution at nucleotide position 205, causing the isoleucine (I) at amino acid position 69 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
