Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 30, 2022The c.670C>G (p.L224V) alteration is located in exon 2 (coding exon 1) of the ISLR gene. This alteration results from a C to G substitution at nucleotide position 670, causing the leucine (L) at amino acid position 224 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
