Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 15, 2023The c.1633A>G (p.I545V) alteration is located in exon 18 (coding exon 17) of the GPCPD1 gene. This alteration results from a A to G substitution at nucleotide position 1633, causing the isoleucine (I) at amino acid position 545 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
