Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.841A>C (p.K281Q) alteration is located in exon 6 (coding exon 5) of the PIH1D2 gene. This alteration results from a A to C substitution at nucleotide position 841, causing the lysine (K) at amino acid position 281 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
