Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2022The c.100C>G (p.P34A) alteration is located in exon 4 (coding exon 2) of the LYG1 gene. This alteration results from a C to G substitution at nucleotide position 100, causing the proline (P) at amino acid position 34 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
