Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.641C>T (p.A214V) alteration is located in exon 5 (coding exon 4) of the PIH1D2 gene. This alteration results from a C to T substitution at nucleotide position 641, causing the alanine (A) at amino acid position 214 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
