Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2023The c.372T>G (p.C124W) alteration is located in exon 4 (coding exon 4) of the GRPEL1 gene. This alteration results from a T to G substitution at nucleotide position 372, causing the cysteine (C) at amino acid position 124 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
