Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 11, 2024The c.325G>A (p.A109T) alteration is located in exon 7 (coding exon 5) of the PHYHD1 gene. This alteration results from a G to A substitution at nucleotide position 325, causing the alanine (A) at amino acid position 109 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
