Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 27, 2022The c.870G>T (p.Q290H) alteration is located in exon 6 (coding exon 5) of the SUSD4 gene. This alteration results from a G to T substitution at nucleotide position 870, causing the glutamine (Q) at amino acid position 290 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
