Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2024The c.546C>G (p.H182Q) alteration is located in exon 3 (coding exon 3) of the QRFPR gene. This alteration results from a C to G substitution at nucleotide position 546, causing the histidine (H) at amino acid position 182 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
