Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 08, 2023The c.3304C>A (p.L1102I) alteration is located in exon 21 (coding exon 20) of the IGSF22 gene. This alteration results from a C to A substitution at nucleotide position 3304, causing the leucine (L) at amino acid position 1102 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
