Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.68C>A (p.S23Y) alteration is located in exon 1 (coding exon 1) of the LRGUK gene. This alteration results from a C to A substitution at nucleotide position 68, causing the serine (S) at amino acid position 23 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
