Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 06, 2024The c.437T>C (p.V146A) alteration is located in exon 5 (coding exon 5) of the IQCH gene. This alteration results from a T to C substitution at nucleotide position 437, causing the valine (V) at amino acid position 146 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
