Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 13, 2024The c.778A>G (p.I260V) alteration is located in exon 6 (coding exon 6) of the LRGUK gene. This alteration results from a A to G substitution at nucleotide position 778, causing the isoleucine (I) at amino acid position 260 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
