Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 26, 2022The c.1756T>A (p.F586I) alteration is located in exon 8 (coding exon 7) of the LRRIQ3 gene. This alteration results from a T to A substitution at nucleotide position 1756, causing the phenylalanine (F) at amino acid position 586 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
