Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.2249C>T (p.A750V) alteration is located in exon 12 (coding exon 12) of the C1orf127 gene. This alteration results from a C to T substitution at nucleotide position 2249, causing the alanine (A) at amino acid position 750 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
