Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2024The c.427C>A (p.R143S) alteration is located in exon 4 (coding exon 4) of the FAM173A gene. This alteration results from a C to A substitution at nucleotide position 427, causing the arginine (R) at amino acid position 143 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
