Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 21, 2023The c.148C>T (p.R50C) alteration is located in exon 4 (coding exon 2) of the PHYHD1 gene. This alteration results from a C to T substitution at nucleotide position 148, causing the arginine (R) at amino acid position 50 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
