Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2024The c.910C>G (p.H304D) alteration is located in exon 9 (coding exon 9) of the IQCH gene. This alteration results from a C to G substitution at nucleotide position 910, causing the histidine (H) at amino acid position 304 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
