Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.538C>T (p.R180C) alteration is located in exon 5 (coding exon 5) of the GPATCH1 gene. This alteration results from a C to T substitution at nucleotide position 538, causing the arginine (R) at amino acid position 180 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
