Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 03, 2022The c.1978C>T (p.R660C) alteration is located in exon 15 (coding exon 15) of the PHTF1 gene. This alteration results from a C to T substitution at nucleotide position 1978, causing the arginine (R) at amino acid position 660 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
