Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.875G>A (p.R292H) alteration is located in exon 5 (coding exon 5) of the IGSF5 gene. This alteration results from a G to A substitution at nucleotide position 875, causing the arginine (R) at amino acid position 292 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
