Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.407G>A (p.R136Q) alteration is located in exon 4 (coding exon 4) of the FAM92A1 gene. This alteration results from a G to A substitution at nucleotide position 407, causing the arginine (R) at amino acid position 136 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
