Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.3742A>G (p.K1248E) alteration is located in exon 22 (coding exon 21) of the IGSF22 gene. This alteration results from a A to G substitution at nucleotide position 3742, causing the lysine (K) at amino acid position 1248 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
