Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2023The c.591C>A (p.H197Q) alteration is located in exon 4 (coding exon 4) of the PXMP4 gene. This alteration results from a C to A substitution at nucleotide position 591, causing the histidine (H) at amino acid position 197 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
